Rory McIlroy took a thinly-veiled swipe at rebel series chief Greg Norman after hitting a superb final round of 62 to retain his RBC Canadian Open title.
McIlroy, who started the day in a share of the lead with Tony Finau, hit 10 birdies in his eight-under-par round to finish two shots clear of the American on 19 under and land his 21st PGA Tour crown.
That is one more than Norman, the CEO of the Saudi-backed LIV Golf Invitational Series, whose maiden tournament finished on Saturday. The PGA Tour has suspended its members who teed off in the event at Centurion Club.
