McIlroy grabs two-stroke lead in Mexico

Rory McIlroy opened up a two-stroke lead at the WGC-Mexico Championship to continue his good form on Thursday.

The world number one, who has started 2020 with two top-five finishes, carded a six-under 65 in the opening round at Club de Golf Chapultepec.

Starting on the back nine, McIlroy made an eagle at the par-five 11th before holing five birdies, with his only blemish coming with a bogey at the fourth.

McIlroy, runner-up last year, is two shots clear of Americans Bubba Watson and Justin Thomas.

"It was good. All aspects of my game were working pretty well. I drove the ball well, and I took advantage of that," McIlroy said.

"I think the big thing was I putted well. I didn't putt so well at Riviera [at the Genesis Invitational] last week. I went back to my old putter, I was trying a new one last week.

"It didn't quite work out the way I wanted it to, but I was comfortable on the greens today and holed some nice ones coming in."

Three-time winner Dustin Johnson endured an awful start by opening with a five-over 76.
