Qualifier Soonwoo Kwon earned his first ATP Tour win on Tuesday at the BB&T Atlanta Open, battling past Indian Prajnesh Gunneswaran 6-7(4), 7-5, 6-0 in two hours and 31 minutes to reach the second round.

“I am really, really happy to win for the first time at an ATP tournament,” Kwon said. “I had lost three times in a row against Gunneswaran, but today I won for the first time against him, so I’m really happy for that.”

Although the pair had never played at tour-level before, Gunneswaran won six of the seven professional sets they had played. Kwon saved all three break points he faced in this meeting.

After the match, ATPTour.com caught up with the Korean — who next plays Cameron Norrie — to learn more about the 21-year-old.

1. The Korean Is Closing On The Top 100, But Is In No Rush
After qualifying in Atlanta and winning his first ATP Tour main draw match, Kwon is projected to reach a career-high ATP Ranking on Monday. His current best is No. 115, which he reached earlier this month.

“I know that I’m really close to the Top 100, but I’m thinking about it step by step,” Kwon said. “It’s no rush. I’m really happy that I’m close to the Top 100, though.”

2. A Loss Against Khachanov At Wimbledon Was A Great Learning Experience
At The Championships, Russian star Karen Khachanov dispatched Kwon 7-6(6), 6-4, 4-6, 7-5 in three hours and seven minutes. Although the Korean did not secure his first Grand Slam main draw triumph, he took a lot out of that defeat, and he believes the experience will help him greatly in the months to come.

“I was losing, but I never gave up in sets and kept trying to fight and come back,” Kwon said. “I learned a lot from that, never giving up on any single point.”

In fact, the 21-year-old wants fans to know one thing about him, it’s that he will always give everything he has every single point.

“I never give up against opponents. I always fight until we have to shake hands,” Kwon said.

3. Kwon Idolises Roger & Rafa
Kwon has not yet gotten to practise with either Roger Federer or Rafael Nadal, but they were his idols growing up. The Korean hopes to play qualifying at the upcoming Coupe Rogers, where he would be ecstatic to work his way into the main draw and compete against Nadal. Federer is not playing that ATP Masters 1000 tournament.

“I’m really close to playing in the same tournaments as them, so I’m really preparing for that,” Kwon said.

4. The 21-Year-Old Is A Video Game Afficionado
Kwon says that he enjoys Playstation, and playing video games after dinner. If he’s not doing that, he added that you can likely find him watching tape of his next day’s opponent.

5. Kwon’s Inspired By Countrymen, Aiming For The Top 10
When Kwon was a junior growing up in Korea, he was not as well-known as some of his countrymen, like Hyeon Chung or Duckhee Lee, who he grew up with. He says they were always more popular, which has motivated him.

“I always try to think about beating them, fighting to get better and better,” Kwon said. “It’s motivation, it gives me a goal to catch up to them.”

Beyond that, Kwon says his ultimate goal is to one day crack the Top 10 of the ATP Rankings.

Former Georgia Tech standout Kevin King walked on Stadium Court Tuesday evening in Atlanta without a tour-level victory. The 28-year-old World No. 405 walked off with not just a win, but a victory against 2017 Nitto ATP Finals champion and former World No. 3 Grigor Dimitrov, whom he defeated 7-5, 6-4 to reach the second round of the BB&T Atlanta Open.

“It’s fantastic. Wouldn’t have rather done it at any other place,” King said. “It was a great crowd out there, great energy, so I’m just thrilled to have won that.”

The week has been extra emotional for King, who received a wild card into qualifying before advancing to the main draw. The lefty’s father, William, had not seed him play for two years before qualifying on Saturday due to a stroke.

“It’s very special,” King said. “It’s been a couple years since he’s seen me play, so just happy that he’s able to come out and support me.”

Before this match, King’s best win came against then-World No. 81 Ernesto Escobedo at an ATP Challenger Tour event in September 2017. Against Dimitrov, an eight-time ATP Tour champion, King earned 23 break points, converting seven of them. The Atlanta resident did well to keep his number of unforced errors down throughout the match.

“It was incredible. It seemed he wasn’t quite at 100 per cent, so it definitely gave me some looks in his service games,” King said. “But I was glad to be able to close it out at the end.”

For a moment, it appeared the Bulgarian may steal the momentum with his back against the wall. In Dimitrov’s final service game, the World No. 53 struck a backhand volley crosscourt that he thought was wide, and he even shook the chair umpire’s hand. But a challenge revealed that it clipped the line, giving Dimitrov new hope.

“I actually thought it was in when he hit it. I was shocked that he was walking to the bench, so I had a little hope that it might’ve been out,” King said. “I was actually surprised it was that close.”

If Dimitrov held that game to even the second set, it could have gotten sticky for King, who has won just six of 21 Challenger matches this season. But the home favourite forced the Bulgarian to beat him, which Dimitrov did not.

“[I] really was just trying to focus on making the return, not trying to get caught up in the score or the moment,” King said. “Just trying to get started in each point and try to make him work.”

It won’t get any easier for King, who will next face second seed Taylor Fritz. The Americans have never met at tour-level, but Fritz defeated King in three sets at an ATP Challenger Tour event last season. As excited as he is to earn the biggest victory of his career, King knows his tournament is not over yet.

“It’s great to celebrate it a little bit now with my friends and family out there, but I’ll go back, do a little recovery and start focussing on the next match.”

Few players have dominated a tournament like John Isner has the BB&T Atlanta Open. The American has won five titles at the ATP 250 tournament and reached the final in eight of nine appearances. But he doesn’t feel any pressure to keep that up this year.

“I think I felt more pressure if maybe I won the tournament two or three times, maybe trying to win it four. And I think now, I’ve won it five times, but that’s a lot, so winning six would be awesome, but if I don’t win it a sixth time this year, that’s okay, too,” Isner said. “I’ve still won the tournament five times… after maybe I won it the first time, or after I lost in the finals the first two years, then maybe I’ll feel some pressure to win it. But not so much right now.”

Isner advanced to the Miami Open presented by Itau final in March after lifting his first ATP Masters 1000 at that event last year. But while playing Roger Federer in that championship match, the American hurt his left foot, ultimately learning that he broke it.

The 34-year-old returned at Wimbledon, where he made the second round. He took a wild card into the Hall of Fame Open in Newport, where he claimed his fourth title. It was even more special because it was Isner’s first title with his daughter, Hunter Grace, in the crowd.

“That was cool. That was actually something I wasn’t even thinking about at all during the course of the match. Thankfully I wasn’t getting ahead of myself, but then when it came time to do the ceremony, I looked at where my wife was sitting. She wasn’t there,” Isner said. “She had gone and got Hunter Grace and brought her over to the side of the court. She was smart enough to go get her and knew that would be a good moment to capture. So that was the highlight of the week, no doubt.”

Three of Isner’s victories came in three sets, with hot and humid conditions making it tough for the players on the grass throughout the week. But having his daughter there made the hard work well worth it.

“After being able to sit down for five minutes straight with an ice towel, I put the ice towel on even after the match was over, so I was very happy the match was over and at that point I was just ecstatic that she got to come out,” Isner said. “She has no idea what was going of course, but in a few years, she’ll be able to look over those pictures and smile.”

In Newport, the ball bounces low on the grass, whereas players have said the Atlanta courts are bouncy. But Isner is not concerned with the quick surface change as he looks to do the Newport-Atlanta title double for the second time.

“I actually don’t think it’s that big of a transition at all. I think if anything it can help. You go from grass where you can occasionally get some tricky bounces to a very pure hard court. I think it makes it pretty easy,” Isner said. “I’m not going to be spending my offseason practising up there or anything, but… I don’t think the transition is that difficult at all.”

Isner will begin his campaign against reigning New York Open champion Reilly Opelka, who owns a 2-1 lead in their budding FedEx ATP Head2Head rivalry. In the 10 sets the Americans have played, eight have gone to tie-breaks.

“It’s going to be very tough,” Isner said. “It could be an actual coin flip… we both serve really well and we both like surfaces like this. So I’m fully aware that I have an extremely tough first match here in my second round.”

American Reilly Opelka set up a tall second-round meeting against top seed and five-time champion John Isner on Tuesday at the BB&T Atlanta Open. Opelka beat Alexander Bublik of Kazakhstan, who fell to Isner in the Hall of Fame Open final on Sunday, 6-3, 7-6(1), behind 17 aces.

“I thought I played really clean,” Opelka said. “I played a really good tie-break, I made all my first serves.”

The 6’11” Opelka and the 6’10” Isner have faced off three times in their FedEx ATP Head2Head series, including three years ago in the Atlanta semi-finals, when Isner won in three sets.

But the 21-year-old Opelka beat Isner twice this year, including in the first round of the Australian Open and in February en route to his maiden ATP Tour title at the New York Open. Eight of their 10 sets have been decided by tie-breaks.

“Coin flip” was how both Isner and Opelka have described their second-round match. “This one probably a little more favoured for John, just because he’s won it so many times,” Opelka said. “Obviously I’m the underdog again playing him, and there’s a good chance there are going to be a lot of tie-breaks.”

Aussie Bernard Tomic knocked out fifth seed Frances Tiafoe of the U.S. 4-6, 6-3, 7-6(4) and will meet countryman Matthew Ebden, who beat Poland’s Kamil Majchrzak 7-6(5), 6-3.

Tiafoe sprinted to a 4-0 lead, but Tomic rallied and saved all three break points in the third set, including two consecutively from 3-4, 15/40.

South Korea’s Soonwoo Kwon, No. 117 in the ATP Rankings, fought back to beat Indian Prajnesh Gunneswaran 6-7(4), 7-5, 6-0, and Brit Daniel Evans breezed past Jason Jung 6-1, 6-1. The 21-year-old Kwon will next meet Brit Cameron Norrie. Evans will face the winner between American Tennys Sandgren and sixth seed Radu Albot of Moldova.

It’s time for a “hot take” on point score to see how good your tennis intuition really is. Here’s a fun quiz that is focused on winning the game in two specific serve and return scenarios.

Scenario 1: Serving at 0/40
You are in the deepest serve hole there is. You need at least five points to hold serve, and for the first three points your opponent is salivating over break points. One slip and you are done.

Scenario 2: Returning at 30/15
Now you need only three points to break serve, while the server needs two. You are much closer to the finish line than the first scenario, but you don’t have the benefit of serving.

Have a think about it… Which scenario offers the highest percentage chance of winning the game?

An Infosys ATP Beyond The Numbers analysis of the current Top 10 from the 2015 season to this week identifies that, on average, they have a higher percentage of winning the game when serving from 0/40. The data set comes from ATP Masters 1000 events and the Nitto ATP Finals.

Current Top 10 Average: Winning The Game
Serving from 0/40 = 19.0% (236/1240).
Breaking from 30/15 = 15.8% (2008/12715)

Eight of the current Top 10 adhered to this pattern, while only No. 9 Daniil Medvedev and No. 10 Fabio Fognini performed better breaking from 30/15.

Current Top 10: Holding from 0/40 – 2015 to Current Week

Roger Federer leads the Top 10 in holding from 0/40 since the beginning of the 2015 season, at 30.4 per cent (24/79). Federer’s gap over second-placed Rafael Nadal is a substantial seven percentage points, or almost a 25 per cent increase. The other two players who were above the Top 10 average of 19 per cent were Dominic Thiem (22.2%) and Novak Djokovic (21%).

Current Top 10: Breaking from 30/15 – 2015 to Current Week

Nadal leads the current Top 10 in breaking from a 30/15 scoreline at 19.8 per cent (280/1417). Djokovic is hot on his heels, breaking 19.5 per cent (300/1528) from this specific scoreline. The other three players above the Top 10 average of 15.8 per cent are Kei Nishikori (17.3%), Roger Federer (16.3%) and Fabio Fognini (16.1%).

Your first instinct was probably to go with the 30/15 point score when returning, as it’s a fairly even battleground and you need only three points to break. But this analysis uncovers just how dominant the serve is. The biggest hole serving is actually not as deep as what you must encounter on the returning side of the equation.

Fifth seed Joao Sousa took another step in turning around his season on Tuesday, beating Belgian Steve Darcis 6-4, 6-4 at the J. Safra Sarasin Swiss Open Gstaad.

The Portuguese saved both break points and will meet Italian qualifier Gian Marco Moroni, who dismissed Spanish wild card Tommy Robredo 6-2, 6-2.

Sousa improved to 17-21 on the season, but he’s 6-2 in his last eight matches. The 30-year-old right-hander reached his second Round of 16 at a Grand Slam at Wimbledon (l. to Nadal) and the quarter-finals at the Swedish Open in Bastad last week.

Spain’s Jaume Munar will meet countryman and top seed Roberto Bautista Agut after rallying from a slow start against Tunisia’s Malek Jaziri 5-7, 6-3, 6-4. Munar, a semi-finalist at last year’s Next Gen ATP Finals in Milan, fell to the Wimbledon semi-finalist last year in Gstaad in three sets, their only FedEx ATP Head2Head encounter.

In other action, Japan’s Taro Daniel won 71 per cent (10/14) of his second-serve points to beat Italian qualifier Filippo Baldi 6-4, 6-4 and will next face 2014 champion Pablo Andujar of Spain.

Albert Ramos-Vinolas will meet fellow Spaniard and second seed Fernando Verdasco for a second straight week after routing Swiss Henri Laaksonen 6-0, 6-3, and Uzbekistan’s Denis Istomin will try to slow down Dusan Lajovic, last week’s Plava Laguna Croatia Open Umag champion, after holding off Swiss wild card Marc-Andrea Huesler 6-3, 7-6(0).

The “Second-Serve Club” has just 18 eligible players so far in 2019, and Rafael Nadal is once again the runaway patriarch.

To be included, players need to have a winning percentage for the season on both Second-Serve Points Won and Second-Serve Return Points Won. It’s no easy task and highlights a specific area of our sport where players can forge an advantage against their opponents.

An Infosys ATP Beyond The Numbers breakdown of second-serve performance, when both serving and returning, uncovers just how impressive World No. 2 Rafael Nadal is in this specific area.

He leads the Tour in 2019 in both statistical categories by a significant margin.

Rafael Nadal: 2019 Season
No. 1: Second-Serve Return Points Won – 56.46%
No. 1: Second-Serve Points Won – 61.3%

When you add both of those percentages together, Nadal’s combined total equals 117.76. That’s head and shoulders above Novak Djokovic, who sits at 111.84. Hot on Djokovic’s tail is World No. 3 Roger Federer, with a combined total of 111.07.

Any time you see Nadal, Djokovic and Federer head a statistical category, it’s time to pay attention. These three players have dominated our sport for a generation, and are showing no signs of slowing down as they currently also occupy the top three spots in the ATP Rankings.

Fresh off the heels of a semi-final run at Wimbledon, Roberto Bautista Agut sits in the fourth spot with a 109.48 combined total. The Spaniard excelled when points started with second serves, winning 58 per cent (102/177) of his second-serve points and 59 per cent (146/249) of second-serve return points at SW19 this year.

Performance around second serves, whether serving or returning, takes into account more of the shots that immediately follow it, as second serves elicit far fewer return errors than first serves. For example, at Wimbledon, almost double the amount of first serves were unreturned over second serves.

2019 Wimbledon
Unreturned First Serves = 39% (6983/18020)
Unreturned Second Serves = 20% (1897/9502)

So when you see outstanding metrics around second serves or second-serve returns, you know the player is very strong defensively in Serve +1 and Return +1 situations. The server is typically on defence with his first shot after a second serve, while the returner is typically on offence with his return from a second serve.

It’s in these moments where Nadal shines the brightest.

2019 Season: Players With A Winning Record On Second- Serve Points Won & Second-Serve Return Points Won

Alexander Zverev broke down the game of in-form Chilean Nicolas Jarry on a sun-kissed Tuesday in an eagerly-anticipated first-round encounter at the Hamburg European Open. The second-seeded German, who made his big breakthrough at the ATP 500 tournament as a 17-year-old in 2014 when he reached the semi-finals, knocked out Jarry 6-4, 6-2 in 72 minutes.

“I had decided to go into the match much more aggressive than in the last encounters we played,” said Zverev. “If you let him into the match he is unbelievably good and can play very aggressively. When he has to move and run a bit, he might become a little worse, but all-in-all it was a very positive first round for me.”

Zverev broke twice in the first set, but could not convert three set points and was broken by last week’s Swedish Open titlist at 5-2. He then won 20 of 25 points from 1-2 in the second set en route to his 26th match win of the year. He will now prepare to face Italian Marco Cecchinato or Federico Delbonis of Argentina.

On 25 May, Zverev saved two championship points to beat Jarry at the Banque Eric Sturdza Geneva Open for the 11th ATP Tour title of his career. The 22-year-old is currently in ninth position in the 2019 ATP Race To London for a spot at the eight-match Nitto ATP Finals, where he is the defending champion. The season finale takes place at The O2 from 10-17 November. Buy Tickets

Zverev’s countryman Jan-Lennard Struff, the seventh seed, struck 10 aces and lost five of his first-service points to sweep past Brazilian qualifier Thiago Monteiro 6-1, 6-3 in 70 minutes. He will next play Spain’s Pablo Carreno Busta, who defeated wild card Yannick Hanfmann of Germany 7-6(5), 6-4 in one hour and 42 minutes.
