#NextGenATP Akira Santillan feels like now is his time to flourish on the ATP World Tour.

The 20 year old recently earned the biggest victories of his career – winning his first ATP Challenger Tour title earlier this month in Winnetka and claiming his first ATP World Tour win at the Dell Technologies Hall of Fame Open in Newport (d. Mmoh).

Santillan has also resolved a nagging dilemma that had been weighing on his mind and affecting his play: Which country should he represent?

The right-hander was born in Japan to his South African father, Dean, and his Japanese mother, Harumi. But the family moved to Australia for Akira’s tennis when he was about seven, and Akira lived Down Under until he was about 18. (He trains in Spain now.)

In early 2015, Santillan decided to play under the Japanese flag. But at Wimbledon, he switched his allegiance to Australia.

“My parents live in Australia. My dad has been living in Australia since he was 13, and I’ve been living there since I was seven… For me, I felt more comfortable playing for Australia,” Santillan exclusively told ATPWorldTour.com. “I’ve been thinking about it for at least over a year now… I felt like I needed to make a decision. I can’t be always wondering in my mind who I’m going to play for, so I think that has cleared things up a bit. It lets me play a little bit freer.”

The relaxed feeling helped Santillan experience his milestone wins in Illinois and Rhode Island. Before Winnetka, Santillan had reached three ATP Challenger Tour semi-finals but he had fallen in the third set during all three. They had been close deciders, too: 7-5, 6-4, 6-4.

In Illinois, after he took the first set 6-4 against German Matthias Bachinger, Santillan later admitted doubts snuck into his mind.

“I was winning comfortably and then I had a hiccup and I found myself in the third set, and I was thinking about it a little bit again,” Santillan said of his past semi-final losses. “But I got through that… I just focused on my game. I was playing really well so there was no reason to be really tight or anything. I went through, won the third set quite comfortably and then the final was pretty straightforward. I played really well, pretty smart tennis. Overall I was really happy with the tournament.”

At the grass-court tournament in Newport, Santillan’s aggressive game thrived as he earned his first ATP World Tour win during his third attempt. “I played really well, and I’m pretty pleased with myself,” Santillan said.

The right-hander’s game favours such quick surfaces. Santillan tries to play an all-around game, a necessity during this era of tennis that has been dominated by do-everything players Novak Djokovic, Andy Murray, Roger Federer and Rafael Nadal.

“I play pretty aggressive with my forehand… I can play anywhere on the court. I like to come to the net. Change pace on my slice. Use my forehand to dominate play. I think I have a pretty good serve, a pretty big serve,” Santillan said. “You need every weapon that you can get. On the tour nowadays, everyone has a weapon – they can defend, they can attack, they’ve got everything.”

Santillan has other big goals to complete this season. The #NextGenATP Aussie, No. 160 in the Emirates ATP Rankings, would like to crack the Top 100. He’d like to qualify for the US Open, the season’s last Grand Slam tournament.

Santillan also might find his way into the Next Gen ATP Finals, to be held 7-11 November in Milan. He is currently in 16^th place in the Emirates ATP Race To Milan, which will determine seven of the eight 21-and-under players who compete at the inaugural event. The eighth player will be chosen by wild card. Santillan is 222 points behind eighth-placed American Jared Donaldson.

“I feel really confident right now with my game. I feel like I’m seeing the ball like a basketball,” Santillan said. “It’s going to be fun and exciting to see how I can do.”

Robin Haase came alive in The Alps once more, just as he has done in two previous runs to the J. Safra Sarasin Swiss Open Gstaad final, when the Dutchman ended David Goffin’s bid for a third ATP World Tour title on Friday.

Haase began in fine style by breaking for a 2-0 lead, and while his top-seeded Belgium opponent stayed in contention, World No. 50 Haase won seven straight games from 5-5 in the first set en route to a 7-5, 6-1 victory in 81 minutes. It was his first win in four meetings against Goffin, the 2015 runner-up (l. to Thiem).

“Today it was a bit more windy and we were both a bit nervous at the beginning,” said Haase. “I really enjoy the conditions here and I’m happy to be back in the semi-finals.”

Sixth seed Haase, the 2013 (l. to Youzhny) and 2016 finalist (l. to Lopez), now faces qualifier Yannick Hanfmann. The World No. 170 could not convert two set point opportunities in the first set, but bounced back to knock out eighth seed Joao Sousa 6-7(10), 6-2, 6-2 in one hour and 56 minutes. Hanfmann, who has played just eight tour-level matches, could not seal set point chances at 7/6 and 9/8 in the first set tie-break.

Second seed Roberto Bautista Agut lost just six of his first-service points to beat Denis Istomin 6-3, 6-4 in 80 minutes to improve to a 31-12 match record in 2017. “Today, the conditions were a bit faster than the other days and Denis played aggressively,” said Bautista Agut. “I will prepare and rest well for tomorrow.”

The Spaniard next faces fourth seed Fabio Fognini, who broke Ernests Gulbis three times to advance 6-3, 4-6, 6-3 in one hour and 50 minutes. Gulbis had led their FedEx ATP Head2Head series 4-1, including 2-0 on clay, before Friday.

Marach/Oswald Advance To Doubles Final
Second-seeded Austrians Oliver Marach and Philipp Oswald booked their place in the Gstaad final by beating third seeds Roman Jebavy and Matwe Middelkoop 6-3, 6-3 in 60 minutes. Marach, 15-21 in doubles finals, partnered Aisam-Ul-Haq Qureshi to the 2015 title match (l. to Bury-Istomin). Oswald will be looking to improve his 4-2 record in finals.

Fourth seeds Jonathan Eysseric and Franko Skugor will take on Dutchmen Sander Arends and Haase in the other semi-final on Saturday.

Novak Djokovic owned 2015. Andy Murray surged to World No. 1 in 2016, and it’s been the Roger and Rafa show so far in 2017.

The Big Four have all had their time in the sun during the past two-and-a-half years, and all are ranked in the Top Four of the Emirates ATP Rankings this week.

An Infosys ATP Beyond The Numbers breakdown of their first-serve percentage when serving down break point in both the deuce and ad courts from the 2015 season to the present time provides deeper insight into the metrics that define their greatness.

1. Overall Record
Novak Djokovic has the highest match-win percentage of the Big Four since the start of the 2015 season, at 88.6 percent, with Roger Federer in second place, at 85.2 per cent.

Big Four Overall W/L Record 2015 to Present

2. Deuce Court – First-Serve Percentage Down Break Point
Nadal is the clear leader in this category, making 73.7 per cent of his first serves in the deuce court down break point. The primary pattern for the lefty is to hit a slice serve down the centre of the court, and follow it up with his trademark “Serve +1” forehand.

Deuce Court – First-Serve Percentage Down Break Point

3. Ad Court – First-Serve Percentage Down Break Point
Nadal leads in this category as well, but it’s interesting to note that he makes just 0.2 per cent more first serves in the ad court than the deuce court. Djokovic improved the most in the ad court over the deuce court, up 4.3 percentage points, while Federer and Murray both made fewer serves on this side.

Ad Court – First-Serve Percentage Down Break Point

4. Overall – First-Serve Percentage Down Break Point
Overall the Big Four played 77.5 per cent of their break points in the ad court. Only Nadal and Djokovic combined to make above 65 per cent of their first serves in both courts during this crucial time of the match.

Overall First-Serve Percentage Down Break Point

5. Summary
Putting a first serve in the court when all the drama is unfolding around a break point comes down to simple technique, holding your nerve, and coming up with the the right serve – a flat, slice or kick serve – and placing it in just the right spot – out wide, at the body or down the centre.

The Big Four don’t always follow the same playbook as each other, but their proven dominance at the top of our sport since the start of the 2015 season comes down to owning moments in time just like this.

Qualifier Federico Delbonis is one match win away from reaching his second final at the German Tennis Championships 2017 after beating third-seeded #NextGenATP Karen Khachanov, currently at a career-high No. 32 in the Emirates ATP Rankings, 7-5, 3-6, 6-4 in two hours and 18 minutes on Friday. Four years ago, No. 81-ranked Delbonis beat Roger Federer in the semi-finals before losing to Fabio Fognini in his first ATP World Tour final. He will next meet lucky loser and 2014 champion Leonardo Mayer or Jiri Vesely in the semi-finals.

Later today, sixth seed Diego Schwartzman plays Florian Mayer, while Nicolas Kicker meet Philipp Kohlschreiber.

After more than a decade of competing together in ATP World Tour doubles events, Thai twins Sanchai Ratiwatana and Sonchat Ratiwatana found themselves battling against each other on Thursday at the BB&T Atlanta Open. 

Sanchai and John Millman moved into the semi-finals over Sonchat and Aisam-Ul-Haq Qureshi 6-2, 6-4. The brothers had only squared off once before at an ATP Challenger Tour event in Cremona in July 2011. Sanchai (w/Mektic) also came out on top in that match over Sonchat (w/Walter).

Sanchai’s win on Thursday marked the first time a Ratiwatana brother has reached an ATP World Tour doubles semi-final since Chennai in January 2013, but they said it’s a moment they’ll still be able to share together.

“It was a good feeling playing each other because it at least means one of us will be in the semi-finals,” said Sanchai. “We talked before the match and said we’re going to give 100 per cent. We just want to improve our games and the result doesn’t matter, so we were actually relaxed out there today.

“Aisam is like an older brother to us. We’ve been practising together and know each other very well,” he added. “I felt no pressure because me and Millman were the underdogs, and it was special for John to turn things around after a tough singles match (against Ryan Harrison).”

The Ratiwatana brothers moved back into the Top 100 of the Emirates ATP Doubles after racking up three ATP Challenger Tour doubles titles this year in Bangkok, Kyoto and Shenzhen, in addition to runner-up showings in Taipei and Busan. They’ve won 44 Challenger doubles titles together, more than any other player on tour, and have won at least one title every year since 2003.

But after dominating the Challenger doubles circuit, they’ve found that being back on the ATP World Tour over the past two weeks has already resulted in significant progress with their tennis.

“Most of the Challengers tournaments we play have singles players competing in doubles, but in tournaments like this, you have lots of doubles specialists and guys like Bob Bryan and Mike Bryan as the top seeds. But even the singles guys competing here hit a much heavier ball than we’re used to.,” said Sanchai. “We’re in a little bit of the comfort zone in Challengers, but just practising with these singles guys and hitting with Millman before his matches will only help me with my game.”

With neither brother having won an ATP World Tour main draw match since July 2014 before arriving in Atlanta, they said they’re open to teaming up with other players again in the future. However, the occasional foray with another player is only for the common goal of reuniting as a full-time partnership on the ATP World Tour

“It’s a good experience for me to spread out and play with someone like Aisam. It’s so hard to get in the ATP World Tour tournaments now with the (Emirates ATP Doubles Rankings) cutoff, so we need to team up with other players or we’ll be stuck playing Challengers forever,” said Sonchat. “We want to play the big tournaments, so we’ll try to get our ranking up and have good results so we can stay on the ATP World Tour together next year.”
