Watson came into this event as British No.1, having surpassed the injured Laura Robson after making the second round of Roland Garros. Former Canadian No.1 Wozniak's season has been highlighted by a fourth round showing at Indian Wells, beating World No.15 Sabine Lisicki in the process.
After losing the first two games, Watson won 10 of the next 11 to go up a set and 4-1. She eventually was up 5-3 and had three match points serving at 5-4, but Wozniak survived them, evened the set and eventually won it. Wozniak continued her momentum in the third set, going up 4-1 before Watson tied it at 4-4. Wozniak then held and broke to finish off the 2-6, 7-5, 6-4 triumph.
By The Numbers
Wozniak actually lost five more points than she won, but won enough of the clutch points to pull out the victory and improve to 2-1 in her head-to-head with Watson.
"Heather played really well," Wozniak said. "I was struggling to find my rhythm out here today, but I just kept trying to fight and play my game, and it got better and better. She played great tennis today and had the home crowd with her, so it was tough."
Wozniak follows up her contest against the British No.1 with a match-up with British No.3 Johanna Konta, whom she has never played.
"Great Britain has so many good players. I'm looking forward to another tough match," Wozniak said of Konta. "She has a great serve. I need to play well from the beginning of the match."
