Ninth seed Jo-Wilfried Tsonga of France could find no solution to the problem of Ivo Karlovic's massive serve as the Croatian ran out a 7-6 6-7 7-5 7-6 victory in their third-round clash at Wimbledon on Friday.
Tsonga failed to create a single break point against the 2.08m player from Zagreb, who blasted 46 aces and has this week spectacularly broken a run of four successive first-round exits at the All England Club.
After sharing the first two sets with tiebreaks, Karlovic carved out the match's only break in the 12th game of the third set to give him the initiative and he clinched the fourth set breaker 7-5 with his final ace after two hours and 44 minutes.
He will play seventh seed Fernando Verdasco of Spain for a place in the quarter-finals.
