Started 2017, his first full season as a professional, 137th in the world, but in under two years made it all the way to second and on his Ryder Cup debut in September defeated Tiger Woods in the singles.
He had won the PGA Tour’s Farmers Insurance Open in 2017 with a closing 60-foot eagle putt, then stormed to a six-stroke victory at the Irish Open and added a one-shot win at the DP World Tour Championship in Dubai. Won his second PGA Tour title at the 2018 CareerBuilder Challenge, beating Andrew Landry in a play-off, then was fourth in The Masters and the PGA Championship as well as winning his home Spanish Open.
Best major finish was his joint third in the recent US Open. As an amateur he reached world No1 and his 23 under par 263 at the 2014 world team championship was six strokes better than the previous record set by Jack Nicklaus in 1960. In December claimed the Hero World Challenge in the Bahamas, in April partnered Ryan Palmer to more success in the Zurich Classic of New Orleans and on July 7 claimed his second Irish Open with a closing 62 at Lahinch.
