Was victorious at the Nordea Masters for a second time in 2015 and the following year claimed four titles during a remarkable season. He won the Aberdeen Asset Management Scottish Open, Omega European Masters, British Masters and Nedbank Golf Challenge in a five-month stretch, which saw him finish third on the Race to Dubai Rankings.

Made his Ryder Cup debut at Le Golf National, Paris, in September 2018, when he rounded off a spectacular European victory in style, holing a monster putt on the final green to defeat Bryson DeChambeau long after Francesco Molinari had sealed the winning point for Thomas Bjørn's team.

Ended a seven-year winless drought as he won the Betfred British Masters for a second time in 2025.
