Rory McIlroy's game appears to be rounding into form.
McIlroy carded an eight-under 63 in Thursday's first round of the 2019 WGC-Mexico Championship, giving him a one-stroke lead over Dustin Johnson. McIlroy and Johnson lapped the field, with no other golfer posting a score better than a five-under.
Justin Thomas and Matt Kuchar are tied for third after shooting 66. Tyrell Hatton and George Coetzee round out the top five after shooting four under.
McIlroy hit 17 of his 18 greens in regulation and had an excellent putting day for his second round of 63 of the past week.
