Abu Dhabi HSBC Golf Championship: Held off final-round charges from Thomas Pieters, Rory McIlroy and Henrik Stenson to win the Abu Dhabi HSBC Golf Championship, marking his second European Tour title. The victory was the first at the event by an American since Chris DiMarco won the inaugural event in 2006. Final-round highlights included a holed bunker shot on the eighth hole (which helped propel him to a three-stroke cushion at the turn), a chip-in for birdie on the 17th hole and then a par on the last to hold off Pieters by one stroke.
Lowry elected to turn professional the week after his Irish Open triumph, meaning that he would miss out on the opportunity to play in the Walker Cup in September 2009. He made his professional début on 28 May at the European Open, where he shot 78 in the first round to end the opening day almost at the back of the field, and went on to miss the cut following a second round 73.
