Rory McIlroy and Caroline Wozniacki went back to work days after McIlroy ended their engagement last week and the results were mixed. McIlroy won the BMW PGA Championship on Sunday, but Wozniacki wasn’t nearly as fortunate. She was bounced from the French Open in the first round Tuesday.

After falling to No. 64 Yanina Wickmayer in three sets, Wozniacki faced the media and gracefully headed off personal questions.

“I don’t really want to talk about my personal life. I hope that you all can understand that,” she said. “The only thing I really have to say is that, you know, [I want to] thank everybody for their support and sweet messages. … What happens in my personal life, I just want to really keep that between my closest people around me. You know, I just have to move on.”

Wozniacki briefly addressed the break-up last week on Twitter and drew support from Serena Williams.

“Obviously, you’re not prepared for something like this and it came a bit as a shock,” Wozniacki said. “I just tried to prepare the best that I could and really tried to focus on my match and on what I had to do out there.”

Wozniacki, the 13th seed, had been fighting injuries and played sparingly in the run-up to the French Open. Then McIlroy called off their five-month engagement just after wedding invitations had been mailed.

“I felt a little bit rusty, and it wasn’t really a pretty match,” she said. “But I tried. … I don’t feel [pain in] my wrist at all, so that’s all good. I could feel my knee a little bit in the extreme situations, but in general I’m positively surprised about how it held up.”
