Rory McIlroy aims dig at Greg Norman after retaining Canadian Open title

• McIlroy: passing Norman's 20 PGA Tour wins extra incentive'
• PGA Tour commissioner also hits out at LIV Series players

Rory McIlroy hit a superb final round of 62 to retain his RBC Canadian Open title before taking aim at Greg Norman, the figurehead of the Saudi-backed LIV Golf Series.

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 breakaway LIV series, managed in his career.
