John Catlin of the USA won his third European Tour title in eight months as he overcame Germany's Max Kieffer in a play-off on the final day at the 2021 Austrian Open at the Diamond Country Club in Atzenbrugg on Sunday. Both men had good chances as the four holes of the play-off were halved but Kieffer found the water three times at the fifth time of asking and Catlin took the crown with a bogey. German Martin Kaymer was three shots out of the play-off at 11 under, three clear of England's Marcus Armitage, Dutchman Wil Besseling and South African Garrick Higgo.
