LA QUINTA, Calif. -- The 59 watch is officially on.
Kevin Chappell is 9 under through 13 holes -- with one par 5, one par 3 and three par 4s remaining. The Californian has moved to 21 under along with David Lingmerth and Brian Gay, which puts the trio four strokes behind Scott Stallings.
A 59 would not be unprecedented at the Humana Challenge in partnership with the Clinton Foundation. David Duval shot one in 1999 when he came from a record seven strokes off the pace to win.
Chappell started the day at 12 under, which was 10 strokes behind Stallings. Chappell's best finish on TOUR is a tie for second at the Valero Texas Open in 2011.
Chappell's lowest round on the PGA TOUR is the 65 he shot in the first round of the Humana Challenge a year ago.
