WIMBLEDON, England (AP) - Ivo Karlovic of Croatia has hit 46 aces in a close third-round upset of No. 9-seeded Jo-Wilfried Tsonga at Wimbledon.
The 22nd-seeded Karlovic never faced a break point Friday and ended his 7-6 (5), 6-7 (5), 7-5, 7-6 (5) victory over the 2008 Australian Open runner-up with an ace.
He will play seventh-seeded Fernando Verdasco of Spain in the fourth round.
Karlovic, the tour leader in aces in 2009, hit a modern-era record 55 in a loss at the French Open last month.
He is best known for stunning 2002 champion Lleyton Hewitt in Wimbledon's first round the following year. The Karlovic lost his opening matches at the All England Club from 2005 to '08.
