Coco Gauff came from a break down in the third set and then won the last six points of the tie-breaker to beat Solana Sierra 6-3, 3-6, 7-6 (7) on Wednesday to reach the third round at Wimbledon.

Gauff was two points away from losing the match when Sierra served at 5-4 in the third set but won three straight points to break back. In the 10-point tie-breaker, she trailed 7-4 but didn’t lose another point, sealing the win with an ace and then screaming out loud with both fists clenched.

“When she had to serve for the match, I just reminded myself that I’m a great returner as well,” Gauff said. “I was just trying to be positive and I think that showed.”
