Rory McIlroy's Scottish Open defence begins with a round of 65

Rory McIlroy bounced back from his US Open heartbreak to make a strong start to the defence of his title at the lucrative Genesis Scottish Open.

McIlroy briefly held a two-shot lead with five holes to play in the US Open but bogeyed three of the last four, missing from two feet and six inches on the 16th and three feet and nine inches on the last to finish a shot behind Bryson DeChambeau.

"It’s just a matter of going out there and focusing on the task at hand and not letting your mind
