LONDON (AP)—Sloane Stephens of the U.S. reached Wimbledon's fourth round for the first time, coming back to close out an uneven 7-6 (3), 0-6, 6-4 victory over 196th-ranked qualifier Petra Cetkovska of the Czech Republic on Saturday in a match suspended the night before because of darkness.

They resumed at the start of the third set, and the 17th-seeded Stephens came out slowly, falling behind 2-0.

But Cetkovska double-faulted three times while letting Stephens take a 4-3 edge. Stephens then held for 5-3, saving a break point with an ace, and later capped the match with a cross-court forehand winner.

At the Australian Open in January, Stephens defeated Serena Williams en route to the semifinals.
