Ivo Karlovic was pretty satisfied with his performance at Wimbledon. The giant Croatian had one of his best Grand Slam showings, reaching the fourth round and going four tough sets against Andy Murray.
He had just one complaint. "It was only 29 aces," said Karlovic, drawing laughter from journalists.
It's an amount most players would be thrilled with, especially against one of the world's best returners. But Karlovic has good reason for keeping track of how many aces he hits these days. During his upset win over Milos Raonic at the Rogers Cup in Montreal on Tuesday night, Karlovic hit his 10,000th career ace. His finished the 7-6 (1), 7-6 (1) victory with four more, and his total of 10,004 is second only to Goran Ivanisevic, who struck 10,183 aces since tour record-keeping began in 1990.
Karlovic knows that he could soon become the King of Aces.
"Yes, I would really, really like to be able to do it, break the record," he told TENNIS.com at Wimbledon. "It will go in the books so of course I would like to do it. He isn't a lot in front of me, and I believe I can do it this season."
Karlovic knows only approximately how many aces Ivanisevic hit, but is being kept informed of his own total by ATP officials, who tell him his updated stats after almost every one of his matches. There's even a target date. "The US Open, maybe—no, I don't know," he laughs. "But this year."
The 36-year-old was 221 aces behind Ivanisevic going into the Rogers Cup, with three tournaments to play through Flushing Meadows. That's almost the same amount of aces he hit in his previous three tournaments, the fast-court events at Wimbledon (grass), Newport (grass) and Bogota (hard). But even if Karlovic fails to set the record on North American hard courts, the slicker surfaces that follow—including those at indoor events—should give him plenty of opportunity if he plays a full season.
Karlovic already leads the way in terms of points won when he gets his first serve in, winning 83 percent of career first-serve points, compared to 82 percent for Ivanisevic and Milos Raonic (as of this week).
Challenging for such records shows how far Karlovic has come since announcing his arrival at Wimbledon 12 years ago, when he stunned defending champion Lleyton Hewitt in the first round. Then a shy unknown with a stutter, Karlovic has since won six singles titles and cracked the Top 15 (in 2008), and has developed a distinctive, more assured personality who regularly shows his humor and enjoys a little attention. His Twitter account, @ivokarlovic, is a hilarious must-follow.
