(January 8, 2015) Croat Ivo Karlovic earned his second win over a No. 1 player on Thursday when he rallied past Novak Djokovic 6-7(2), 7-6(6), 6-4 to reach the semis of the Qatar Open on Thursday.
Karlovic, who surpassed the 9000 ace mark earlier in the week, fired 21 aces past his Serbian opponent, along with 49 winners. His career ace count is now up to 9,062.
“It was unbelievable,” said Karlovic in an on-court interview. “When I arrived here, I didn’t expect that one. He wasn’t able to show his full range because it was windy. I just focused on my game and in the end I was a little luckier.”
Karlovic last defeated a No. 1 player back in 2008 when he stopped Roger Federer at the Western & Southern Open.
Karlovic will face off against David Ferrer in his semifinal.
