Robert Macintyre hones in on RBC Canadian Open win after securing four shot lead

The 27-year-old looked in trouble early, opening with a bogey and going around the turn at one over.

A birdie on the 10th returned him to even par, but another dropped shot on the 13th threatened to derail his hunt for his first PGA Tour title.

He recovered masterfully, however, carding three straight birdies before sinking a 30-foot putt for eagle on the par five 17th to head into the clubhouse on 14 under.

Macintyre leads by four strokes from the trio of Mackenzie Hughes, Ryan Fox and Ben Griffin.

England's Tommy Fleetwood is a shot further back on nine under after soaring up the leaderboard with a bogey-free round of 64 on Saturday.

Meanwhile, Rory McIlroy fired himself back into contention with a five-under round of 65.

The Northern Irishman moved back into the top 10 on seven under after a front-nine scoring blitz at the Hamilton Golf and Country Club.

"There are still some low scores out there. It felt like it could've been better but I got myself back into the tournament and hopefully within touching distance of the guys going into tomorrow," he said in his post-round interview.

"I had a quick range session last night and felt that reset me. I just felt like my swing was a little out of sync with everything, so I just worked on a little bit of tempo and rhythm."
