Caroline Wozniacki defeated Camila Giorgi in straight sets at the Nature Valley International on Monday, winning 6-2, 6-3.
The top seed advanced to the third round after only 76 minutes of play, despite an early break by Giorgi.
The 2009 champion fought hard and went on to win the last six games of the opening set, striking 14 winners to 11 unforced errors during the match.
Wozniacki said: "You need to get into the rhythm of the match, and it took me a few games but then it felt really great to be back out here.
"She started off well. I didn't get a first serve in on my first service game, and I was kind of in trouble. I was lucky to break her back to that 2-1 game, and then I kind of found my way into the match and started playing some good tennis.
"She hits the ball very hard and she has big serves, but for me, it's about waiting for the one moment where I had an opportunity and then trying to get that one. Even though the score says 6-2, 6-3, it was a tough match and tighter than the score suggested."
The Danish player will now face either Libéma Open winner Aleskandra Krunic or British No.1 Johanna Konta.
Elsewhere, Kristina Mladenovic was able to recover from a set down to beat Heather Watson in three sets 6-7(2), 7-5, 6-3.
