NEW YORK — American Sloane Stephens overcame numerous deficits Monday to pull out a 4-6, 6-3, 7-6 (5) victory over Mandy Minella of Luxembourg in the first round of the U.S. Open.

Stephens, seeded 15th, lost the first set to the 110th-ranked Minella and trailed 4-2 in the third, then 3-1 in the final-set tiebreaker.

Stephens won five straight points from there, then closed it out on her third match point to improve to 9-1 in the first rounds of majors.

This was the second time in three years Stephens needed a third-set tiebreaker to win her opening match at Flushing Meadows.

Stephens made her first career Grand Slam semifinal earlier this year at the Australian Open, then followed that by making the fourth round at the French Open and quarterfinals at Wimbledon.
