Kevin Na leads the Fort Worth Invitational by one over Charley Hoffman following a first-round 8-under 62. Here's where things stand through 18 holes at Colonial.
Leaderboard: Na (-8), Hoffman (-7), Emiliano Grillo (-6), Jhonattan Vegas (-6), Andrew Putnam (-6), Beau Hossler (-6)
What it means: The veteran Na is in search of just his second PGA Tour victory in 367 events played. The 34-year-old's lone victory came at the 2011 Shriners to go along with nine runner-ups, the most recent of which was a tie for second at this year's Genesis Open.
