Ben Curtis stumbled to a pair of double- bogeys on Saturday, but still managed to extend his lead to three strokes after 54 holes of the Texas Open.
Curtis managed a one-over 73 to finish three rounds at nine-under-par 207. He will go for his fourth PGA Tour title on Sunday.
Matt Every also shot 73 to slip to minus-six on the AT&T Oaks Course at TPC San Antonio. He is alone in second and is chasing his first PGA Tour title.
John Huh was in the first group out Saturday morning and he fired a five-under 67 to match Matt Kuchar for the low round of the day. Huh soared 37 places into a share of third place at four-under-par 212. He was joined there by Charlie Wi (71) and Seung-yul Noh (68).
The third round is known as moving day in golf. On this day, most of the moving was the wrong direction as just 19 of the 81 players that made the cut broke par.
Of the nine players in the final three groups, Wi was the only player to shoot under par.
Kuchar, who leapt 41 places into a tie for sixth, stands alongside Brian Gay (71), Greg Chalmers (69), David Mathis (77) and Cameron Tringale (76) at minus-three .
