WINSTON-SALEM, N.C. (AP)—Guillermo Garcia-Lopez battled through a third-set tiebreaker before beating 11th-seeded Donald Young of the 6-7 (4), 6-3, 7-6 (6) on Wednesday in the third round of the Winston-Salem Open.

Garcia-Lopez, the tournament's fifth seed, overcame a 6-4 deficit in the third tiebreaker by winning four consecutive points in the final tuneup before next week's U.S. Open.

''The last month in Europe on the clay courts, I was losing a lot of tiebreakers,'' said Garcia-Lopez, who won his third career ATP Tour title last April in Morocco.

''But at the end today, I got lucky. Sometimes the tiebreaker is a lottery, and I got the number. That's why I won.''

After Young took the first-set tiebreaker, Garcia-Lopez broke Young's serve twice in winning the second set, and used another service break to take a 5-3 lead in the third set with a chance to close things out.

After holding serve to close within 5-4, Young overcame two match points — the second on a leaping overhand volley that Garcia-Lopez put into the net — to get his own service break and tie the match at 5-5 in the third set.

''It was just reacting — I really wasn't thinking,'' Young said. ''I just wanted to get the ball back, and did what I had to do to get it back. It was definitely exciting to save a match point that way, but the big picture didn't happen the way I wanted it to."

In the third-set tiebreaker, Young led 4-1 and 6-4, aided by a pair of mini-breaks on Garcia-Lopez's serve. But Garcia-Lopez held serve to pull within 6-5, then pulled ahead off a pair of mini-breaks on Young's serve.

In other matches Wednesday at the Wake Forest Tennis Center, Belgian qualifier David Goffin extended his winning streak to 25 matches by taking a 6-4, 4-6, 6-4 victory over 15th-seeded Jarkko Nieminen of Finland.

Also advancing to Thursday's quarterfinals were Poland's Jerzy Janowicz, a 4-6, 6-3, 6-4 winner over 12th-seeded Edouard Roger-Vasselin of France; seventh-seeded Lukas Rosol of the Czech Republic defeated No. 10 seed Pablo Andujar of Spain 1-6, 6-2, 6-2; ninth-seeded Yen-Hsun Lu of Taiwan beat No. 8 seed Marcel Granollers of Spain 6-1, 6-2; and 14th-seeded Andreas Seppi of Italy downed France's Nicolas Mahut 6-4, 7-6 (7).

Scheduled to play later Wednesday was American John Isner, the tournament's top seed and two-time champion.
