Marin Cilic beat American Sam Querrey 17-15 in the fifth set after five hours and 31 minutes of play Saturday to reach Wimbledon's fourth round for the first time since 2008.
The 16th-seeded Cilic got the pivotal break at 15-15 in the fifth set when the 64th-ranked Querrey double-faulted, then put a forehand into the net.
Cilic then served out the marathon match, winning 7-6 (6), 6-4, 6-7 (2), 6-7 (3), 17-15.
This was the second-longest singles match in Wimbledon history. The record is the 11 hours, 5 minutes for John Isner's 70-68 fifth-set victory over Nicolas Mahut in 2010.
