SAN MARTIN, Calif. (AP) -- John Mallinger opened a four-stroke lead Friday in the Frys.com Open, making an eagle and two birdies on the final four holes for a 9-under 62.
Mallinger eagled the par-5 15th and closed with consecutive birdies to cap his second straight bogey-free round and reach 14 under at CordeValle Golf Club.
Billy Horschel and Jhonattan Vegas were second. Horschel had a 65, and Vegas shot 67.
First-round leader Nick O'Hern followed his opening 62 with a 71 to drop into a tie for fourth at 9 under with European Ryder Cup player Nicolas Colsaerts and Scott Dunlap. Colsaerts had a 68, and Dunlap shot 63.
Colsaerts is a special temporary PGA Tour member and needs to finish the equivalent of 125th on the money list to earn a full 2013 card. The Belgian player has earned $652,886, enough now for the 120th spot.
British Open winner Ernie Els was 3 under after a 68.
