Drive for show, putt for dough, right?
After a great drive on the par-4 ninth hole, Rory McIlroy struggled on the green.
It took McIlroy four putts to finish the hole, and he saw his lead disappear. It spoiled what was otherwise a solid opening nine, with three birdies on his card.
Dustin Johnson now leads McIlroy by one shot during the second round of the WGC-Mexico Championship.
