Finding a rhythm on serve proved a challenge for both competitors. The two each went nine for 16 on their break point chances and in addition to Gauff’s problems at the line, Collins herself double-faulted 13 times.
The former Australian Open finalist nearly pulled off her second win over a world No. 2 this season. Having twice erased a break deficit in the decider, Collins served for the match at 6-5 but couldn’t string together the right sequence of points in losing the two-deuce game.
Gauff soon ran away with the final five points of the first-time meeting, ironically finishing with an ace out wide to prevail after two hours and 56 minutes.
This is the 21-year-old’s first tournament since going 0-2 on grass that ended with an opening defeat at Wimbledon to Dayana Yastremska. Veronika Kudermetova, who knocked off 29th seed Olga Danilovic 6-4, 6-2, awaits Gauff in the third round.
