McIlroy posted his lowest round of the week on Sunday, a 6-under 66, en route to a one-shot victory over childhood friend Shane Lowry (68) at the European Tour’s flagship event. It was his sixth European Tour victory, his first on European soil and his first since November 2012, when he won the DP World Tour Championship.
The win came just four days after the 25-year-old announced he and his tennis star fiancé broke off their engagement.
“I’m not exactly sure how I’m feeling right now, to be honest," McIlroy said. "I’m happy that I won, obviously. … Mixed emotions.”
McIlroy mounted the largest final-round comeback of his career; he came from seven shots back of 54-hole leader Thomas Bjorn. McIlroy got off to a hot start with an eagle at the par-5 fourth hole, then added six birdies to just two bogeys on the day. Before the win, McIlroy's best finish at the BMW PGA was a fifth-place finish in 2009.
McIlroy's last worldwide victory came at the Australian Open in December 2013, where he also shot 66 in the final round to win by one over Adam Scott. It was later that month, on December 31st, that McIlroy asked for Wozniacki's hand in marriage.
Finishing two shots back of McIlroy were Bjorn (75) and former world No. 1 Luke Donald (70).
