John Isner blasted 26 aces en route to a 4-6, 7-6 (5), 6-4 win over Cam Norrie in the first round of the Masters 1000 event in Cincinnati on Tuesday, becoming just the second man to cross 13,000 career aces since the ATP began tracking the stat in 1991.

Isner came into Cincinnati with 12,978 career aces and now has 13,004. He’s just the second man to pass 13,000, after Ivo Karlovic, who’s hit 13,709 in his career.

“I do know that I’m within shouting distance of Ivo, of maybe getting that record,” Isner told “I would like to hold that record… We’ll see if I can get there.”
