Ivo Karlovic reaches another ace milestone in advancing to the Wimbledon fourth round.

Karlovic Strikes 41 Aces To Set Murray Clash

Ivo Karlovic and Andy Murray will battle in the Round of 16

Ivo Karlovic hammered 41 aces en route to clinching his third Round of 16 berth at Wimbledon, edging 13-seed Jo-Wilfried Tsonga 7-6(3), 4-6, 7-6(2), 7-6(9) on Saturday.

The big-serving Croat rained down more than 40 aces for a third consecutive match, a tour-level record (since 1991). Amassing a total of 136 in three matches this week, Karlovic is now 77 shy of countryman Goran Ivanisevic's tournament-high 213, which was achieved during the former World No. 2's title run in 2001.

"I know every game is different," said Karlovic. "I always try to begin good and if it's a lot of aces like this, then of course it is easier. Each point is a new one, so I don't feel like nobody can beat me. I just always go on to the next one."

Karlovic won his 13th tour-level tie-break of the year in capturing the opener 7-6(3), but Tsonga's response was swift, drawing level after securing the first break of the match in the fifth game of the second set. Karlovic would claim another tie-break to take a two-sets-to-one lead and a third to close out the match after two hours and 51 minutes.

The 23rd seed won an impressive 90 per cent (89/99) first serve points, firing a total 83 winners. He would convert on his third match point in the deciding tie-break.

"It's not easy because even when he doesn't hit the ball really hard, it's coming from very high," said Tsonga. "So the bounce is different as usual. That's why he's so difficult to return." 

At 36, Karlovic is the oldest player to reach the Round of 16 at the All England Club since fellow Croat Niki Pilic advanced as far in 1976. He will face home hope Andy Murray in the fourth round after the 2013 champion overcame Andreas Seppi 6-2, 6-2, 1-6, 6-1 in two hours and eight minutes.

Murray suffered a momentary hiccup after cruising through the first two sets, and he would reel off 18 of the next 23 points after calling for the trainer (right shoulder) early in the fourth. He secured seven breaks in 12 chances, firing 32 winners and 10 aces.

The third seed is on an eight-match winning streak having claimed his fourth Aegon Championships crown at Queen's Club two weeks ago. He will look to improve on his 5-0 FedEx ATP Head2Head edge over Karlovic, having previously earned a four-set win in the 2012 Wimbledon second round.

"He served extremely well this tournament," said Murray about Karlovic. "A couple matches here where he served over 40 aces. In Halle, as well, he served I think the record for three sets with his match with Berdych. Extremely tough match. I'll need to be very sharp on my returns and try and find a way to get as many of his serves back in play as possible and see what happens. But it's obviously a very, very tricky match."

Seppi was bidding to topple a Top 3 seed in a Grand Slam for the second time this year after stunning Roger Federer at the Australian Open.
