John Isner hit 12 aces during his 3-6, 6-4, 6-4 loss to Gael Monfils in the Montpellier quarterfinals, bringing his total for the season to 1,011.
Isner joins Goran Ivanisevic, Ivo Karlovic, Pete Sampras and Andy Roddick as the only players to break the 1,000 aces mark in a single season. Ivanisevic holds the record with 1,477 aces, set in 1996.
"...it wasn't a goal I set for myself to hit more than 1,000 aces, but I knew coming into these last three tournaments that I was close and that I was very likely to reach it," said Isner. "It's been the case today and it's pretty neat being in the company of these four really good players."
Over 100 of those aces were hit in Isner's record-breaking match against Nicholas Mahut at Wimbledon.
