US Open champion Jon Rahm warned his rivals he still has room for improvement after claiming a share of the lead in the £5.8million abrdn Scottish Open.

Rahm shrugged off a bizarre incident on his opening hole at the Renaissance Club, when a spectator nonchalantly walked on to the 10th tee and took a club out of playing partner Rory McIlroy’s bag, to race to the turn in just 29 shots.
