Harris English closed with back-to-back birdies, the last of them a 25-foot chip-in to seize a one-stroke lead after the second round of the USPGA Mayakoba Classic.
English on Saturday fired a bogey-free seven-under par 64 at Playa del Carmen, Mexico, to stand on 13-under 129 after 36 holes with Vaughn Taylor second on 130 and Brendon Todd another stroke adrift.
"Might have missed two greens today," English said.
"Just hit it well. Iron game was on. Wedge game was on and I got hot with the putter a little bit. It was awesome.
"I feel like if I keep playing like this, I'm in a good spot."
"When you get one to go in like that, it's icing on the cake."
