Rory McIlroy captured his 20th career US PGA Tour title on Sunday, firing a six-under par 66 to win the CJ Cup by one stroke over Collin Morikawa. 

Disappointed by a poor performance at last month’s Ryder Cup and his struggles after trying to match the long-distance driving of Bryson DeChambeau, the 32-year-old from Northern Ireland showed the form that made him a four-time major champion.
