Ivo Karlovic fired down aces – as only he can – on Wednesday to become the oldest player to reach the Australian Open third round in 40 years.

Karlovic, who turns 39 next month, came through the longest match of the tournament so far with 53 aces in a 7-6(3), 6-7(3), 7-5, 4-6, 12-10 victory over Japan’s Yuichi Sugita in four hours and 33 minutes.

“I‘m happy, but also very tired,” said 6’11” Karlovic, who towered over 5’9” Sugita. “I was already feeling it at the beginning of the third set, but I just focused on my serve.”

The Croatian, who will now take on Italian Andreas Seppi, will be the oldest player to compete in the third round since Australian great Ken Rosewall, aged 44, in 1978, when the draw was 64 players. Karlovic is the oldest player in the Australian Open third round since the advent of a 128-player draw in 1982.

Karlovic saved four break points in the second game of the deciding set, then broke in the 21st game of the set after Sugita made a forehand error. He finished the match with a backhand volley, his 110th winner.

Looking ahead to playing Seppi, Karlovic said, “It’s going to be very tough because he returns unbelievably. I will try to play my game and we will see. It’s going to be very hot and that will make my serve a little faster. But it will not be easy.”

Last year, at Melbourne Park, Karlovic sent down 75 aces in a 22-20 fifth-set first-round victory over Horacio Zeballos of Argentina. Read More

Grigor Dimitrov survived a huge test at the Australian Open to defeat qualifier Mackenzie McDonald 4-6, 6-2, 6-4, 0-6, 8-6 on Wednesday. Dimitrov found himself in serious danger against McDonald, who had never previously faced a player ranked higher than No. 69 in the ATP Rankings, but came through in three hours and 26 minutes.

Dimitrov, who reached the semi-finals last year, bounced back from losing the fourth set 0-6, and, as the pressure increased, the Bulgarian used his big-match experience to convert the lone break point opportunity of the fifth set for a memorable win over the World No. 186.

“I fought through the match. I had to find a way to win. It was simple as that,” said Dimitrov. “The game wasn’t there today. I wasn’t feeling well on the court. My movement was a little bit out of sorts…but I won with what I had. That was my fighting spirit, the experience. When it got to those tight moments, I thought I just played well.”

The reigning Nitto ATP Finals champion struggled to win points behind his second serve (13/46) and hit nine double faults in the match, but found a way, with the help of 48 winners to write his name in the last 32 of the draw. Dimitrov has now reached the third round for the fifth consecutive year, after avoiding a loss to a player ranked outside of the Top 100 for the first time at a Grand Slam.

Escaping the fate of consecutive second-round losses at a Grand Slam, Dimitrov moves on to the third round where he will meet Andrey Rublev, the player responsible for his round of 64 loss at the 2017 US Open. The #NextGenATP star won, after the Russian battled past 2006 finalist Marcos Baghdatis 6-4, 6-7(5), 6-4, 6-2.

McDonald was quick off the mark in set one, converting what would be his only break point in the third game. Losing just three points behind his first serve and playing without fear, the young American saved two break points in the eighth game before converting his third set point to lead the 2017 semi-finalist.

“I have to give him credit. He came out there and started swinging. Played an unbelievable first set. There was honestly not much I could have done. He was serving well, close to the lines, swinging freely, coming to the net, trying to play a different game. In a way, he knew that was the only way he could actually give me a trouble,” said Dimitrov.

Order was soon to be restored in the second set however, as Dimitrov limited his opponent to just two winners, six times less than he had conceded in the opening set. The reigning Nitto ATP Finals champion broke in consecutive McDonald service games to close out the set and even the scoreboard.

The third set would once again see 22-year-old McDonald take an early lead. Dimitrov saved two break points with phenomenal defensive and attacking forehands at 2-2, but could not save a third, as his forehand was confirmed by Hawk Eye to have fired wide. The third seed battled back immediately in the next game with a stunning forehand passing shot to level the set once again at 3-3. In the tenth game, Dimitrov would capitalise on forehand errors before taking a two-sets-to-one lead with a forehand winner.

For the third time in four sets, Dimitrov would relinquish the initiative early. Double faults and forehand errors from Dimitrov would help McDonald, who won his first tour-level match on Monday, earn a stunning 6-0 fourth set to force a decider.

“I played a very sloppy game, the first game,” admitted Dimitrov. “I drifted away on that set. I just felt if I could have had maybe another look or break back, things would have been different. After that, the set just kind of run away from me.

“A lot of the shots that he was hitting on the run, especially on the run on the forehand, they were passing sometimes millimetres over the net. Honestly, there’s not much more I could have done in that particular set.”

The fifth set would see both men produce incredible levels of serving and composure, with none of the first 11 games going to deuce. McDonald passed the first real test of the set, serving to stay in the match for a second time at 5-6, but held his nerve when two points from defeat at 0/30 and deuce.

Dimitrov however, would not be denied two games later. The pressure began to tell on McDonald, who dropped to 0/30 and, although he won three straight points, Dimitrov raised his game with a stunning backhand winner. A double fault and forehand into the net from McDonald followed, bringing the blockbuster to an end with Dimitrov roaring in celebration in front a capacity crowd just before midnight local time.

Addressing concerns over how his body will react to such a tough match early in the event, Dimitrov was confident about his ability to recover and focussed, philosophically, on the positive aspects of such a hard-fought win.

“The body feels well, so that’s a good sign,” assessed Dimitrov. “I don’t feel I wasted that much energy, even though I stayed over three hours on the court.

“That’s the beauty of tennis, you always get another day. Every day is different. It’s a two-week tournament. Anything can happen. Right now I’m just positive, happy with the situation. To win ugly.”

Twelve months ago, on Hisense Arena, Nick Kyrgios lost a two-sets-to-love lead to succumb 10-8 in the fifth set to Andreas Seppi in the second round. On Wednesday, there was to be no repeat of that bitter disappointment at the Australian Open.

Kyrgios overcame Serbia’s Viktor Troicki, on the same stadium court, in a performance typical of the Australian’s great start to the 2018 season, which includes his fourth ATP World Tour crown at the Brisbane International presented by Suncorp (d. Harrison).

The 22-year-old Kyrgios failed to serve out the match at 5-4 in the third set, but came through a big-hitting encounter 7-5, 6-4, 7-6(2) in two hours and 12 minutes.

Kyrgios sets up a third-round test against 2008 finalist and No. 15 seed Jo-Wilfried Tsonga of France, who earlier in the day rallied from a 2-5 deficit in the fifth set to defeat #NextGenATP Canadian Denis Shapovalov. Tsonga beat Kyrgios in their lone FedEx ATP Head2Head meeting at the 2017 Open 13 Marseille.

Kyrgios, the No. 17 seed, overcame nerves at the end when he failed to convert one match point at 5-4, with Troicki serving at 30/40 in the third set. Subsequently broken in the next game, Kyrgios managed to re-group in the tie-break to win six of the first seven points.

At 1/4 in the tie-break, Troicki mis-hit a return which struck chair umpire James Keothavong in the head. Drawing a smile from Keothavong, the umpire, much to the delight of the capacity crowd, announced, “It’s not my day, is it?”

Kyrgios finished with a backhand, one of 38 winners – including 17 aces – to remain unbeaten this year (6-0 record). Troicki had been attempting to record his 50th match win at a Grand Slam championship.

Pablo Carreno Busta became the first player to advance to the third round at the 2018 Australian Open when Tata Open Maharashtra champion Gilles Simon retired while trailing 2-6, 0-3.

Carreno Busta reaches his fifth consecutive Grand Slam third round, after reaching the quarter-finals and semi-finals at Roland Garros and the US Open, respectively last year. Simon led 2-1 in the first set and held a total of four break points in Carreno Busta’s first two service games, but the No. 10 seed won the next eight games before Simon retired.

The pair entered their second-round encounter with an even 2-2 FedEx ATP Head2Head series record, with Simon winning their only previous match on hard court in straight sets (2016 Shanghai). The Frenchman entered the season’s first major with momentum after earning his first ATP World Tour title since the 2015 Open 13 Marseille (d. Monfils). In Pune, Simon beat three Top 20 players in the ATP Rankings, including World No. 6 Marin Cilic in the semi-finals.

Carreno Busta will play No. 23 seed Gilles Muller, who survived a tremendous comeback by Malek Jaziri 7-5, 6-4, 6-7(5), 3-6, 6-2 to win two matches in a row for the first time since July 2017 (Atlanta).

For a moment, it appeared that Jaziri would come back from two sets down for the second match in a row after defeating Salvatore Caruso in that fashion on Monday. After failing to break Muller in the first three sets of the match, the Tunisian snuck out the third-set tie-break before breaking on his fourth opportunity in his opponent’s first service game of the fourth set — his eighth chance overall. And with his forehand catching fire from the baseline, Jaziri stormed ahead with the momentum, losing just two more points on serve in the rest of the set to force a decider.

Muller, who last season won his first ATP World Tour title immediately before the Australian Open at the Sydney International, entered the first Slam of the year in 2018 having gone 4-7 in his past 11 matches. He also had never lost a set in two previous FedExATP Head2Head meetings against Jaziri. Yet suddenly, after coming within a game — twice — of advancing to the third round in straight sets, Muller was in deep trouble, falling behind a break at 0-1 in the fifth set.

But the 34-year-old, competing for the 12th time in the Australian Open main draw, broke Jaziri twice in a row to right the ship. While the World No. 100 earned five break points trailing 1-3, Muller gave him little opportunity to take advantage, using his pinpoint left-handed serve to end points or allow him to control them with his forehand. After four hours, two minutes and on Muller’s fourth match point, Jaziri shuttled a backhand down the line wide to end the back-and-forth battle.

While Muller defeated Carreno Busta at the 2015 Australian Open, the Spaniard beat Luxembourg’s star player in last season’s Millennium Estoril Open final to win one of his three ATP World Tour titles. He also leads his FedEx ATP Head2Head series 2-1 against the crafty left-hander.
