Tyrrell Hatton began the defense of his Abu Dhabi Championship title by shooting 6-under 66 and was three strokes off the lead in second place midway through the first round on Thursday.

Rory McIlroy got off to a disappointing start to his first event of 2022, though, bogeying his final two holes for an even-par 72 at Yas Links, which was hosting the Rolex Series event on the European tour for the first time.
