HAMBURG, Germany (AP) Top-seeded Rafael Nadal toiled to beat Jiri Vesely 6-4, 7-6 (2) to reach the Hamburg Open quarterfinals on Thursday.
Nadal's quarterfinal opponent will be fifth-seeded Pablo Cuevas of Uruguay, who outlasted Jerzy Janowicz of Poland 6-3, 4-6, 6-2.
Nadal appeared in trouble when he dropped his serve for 4-4 in the second set. But he broke right back and served for the match, only to commit a double fault at match point. He served another double fault to drop the game, but Vesely could not take advantage and Nadal cruised through the tiebreaker, winning the match when Vesely netted a backhand.
