Charlie Wi shot an 8-under 64 in round one to grab the lead at the 2012 Children's Miracle Network Classic on Thursday at the Walt Disney World Resort.
Wi has a one-stroke lead over Tommy Gainey and Camilo Villegas, who both shot a 65.
Wi grabbed the first-day lead thanks to back-to-back birdies on the final two holes. He's had a first-round lead three times this year, but he hasn't won on the PGA Tour yet.
Brian Harman, Scott Stallings and Russell Knox each shot a 66 to tie for fourth after the first round.
