Rory McIlroy’s personal life was on shaky ground early this week at the BMW PGA Championship at Wentworth, but by Sunday he proved that his golf game is still rock solid by winning one of the European Tour’s most prestigious events.

McIlroy announced on Wednesday that he had split with his fiance, Danish-born tennis star Caroline Wozniacki, putting the No. 10-ranked golfer in the Official World Golf Rankings in a precarious state of mind at Wentworth.

“I’m not going to lie. It’s going to be very difficult,” McIlroy said on Wednesday, when asked if it would be hard to concentrate on his golf this week. “But you know, at least when I get inside the ropes, just try and concentrate on the shot at hand.”

After his opening round of 68, McIlroy said that he’d “be delighted to make it to the weekend,” a feat he hadn’t accomplished since 2011 when he finished tied for 24th. But McIlroy did much more than that, firing rounds of 71 and 69 to put himself within seven shots of the lead heading in the tournament’s final round.

A 6-under 66 on Sunday leapfrogged McIlroy two shots ahead of third-round leader Thomas Bjorn, who held a four-shot lead entering Sunday but imploded with a 75, as well as Shane Lowry, who finished one shot back of McIlroy at 13-under.

McIlroy has been winless on the PGA Tour since the 2012 PGA Tour Playoffs and had not won on the the European Tour since the DP World Tour Championship in Dubai in November 2012. But his strong play in 2014 indicated that he was much closer to winning form than his record showed.

The 25-year-old has finished no worse that 25th on the PGA Tour in eight stroke play events, which included six top-10 finishes including a T8 at the Masters and a T7 at The Players Championship.

With the U.S. Open only three weeks away, McIlroy should be one of the heavy favorites at Pinehurst No. 2, where he’ll try to win his third major championship.
