USA

In March became, at 47, the oldest winner of a World Golf Championships event when he beat Justin Thomas in a play-off at the Mexico Championship.

It was the left-hander’s 43rd PGA Tour title, but first since the 2013 Open at Muirfield, where his closing 66 gave him his fifth major by three from Henrik Stenson. Three years later at Royal Troon the pair fought out an amazing duel, Mickelson equalling the then major record with his second round 63, but Stenson matching that on the final day to triumph by three with JB Holmes 11 strokes further back in third. Of the four majors only the US Open has eluded him and he has been second in that a record six times - most agonisingly in 2006 when he double-bogeyed the last hole to lose by one to Geoff Ogilvy.

America's most experienced Ryder Cup player with 11 caps, his Open victory came a week after he captured the AAM Scottish Open at Castle Stuart and he also had success in Scotland alongside Mark O'Meara and Steve Stricker in the 1996 Alfred Dunhill Cup at St Andrews. Played his 100th major at the PGA Championship last August.
