Jason Kokrak shot even-par 70 on Sunday to outduel Jordan Spieth and notch a two-stroke victory at the Charles Schwab Challenge in Fort Worth, Texas.
Kokrak finished at 14-under 266 while recording his second career PGA victory. He also won at Shadow Creek last October.
Spieth shot 3-over 73 while falling short in his bid for his 13th career victory.
The Dallas native had the overwhelming support of the fans who lined up around the greens at Colonial Country Club, but Kokrak spoiled the hometown celebration.
"I don't know if it motivated me or not but I told myself like the last time - just stay patient, one shot at a time," the 36-year-old Kokrak said. "That sounds like everybody else, but you know, you can't get ahead of yourself inthis game. This game doesn't owe you anything, and you know, you take each shot for what it is, whether you make a bogey or a par or a birdie."
Charley Hoffman shot a sizzling 65 to finish in a four-way tie for third at 10under. Patton Kizzire (67 on Sunday), Colombia's Sebastian Munoz (68) and England's Ian Poulter (68) also finished four shots back.
Troy Merritt also shot 65 to match Hoffman for the low round on Sunday. Merritt was alone in seventh at 7 under.
Despite carding bogeys on 15 and 16, Kokrak took a one-shot lead to the18th.
But Spieth hit his tee shot into the right rough and his second shot was disastrous, sailing past the hole and the green to the left and dropping into the water hazard.
Spieth eventually got the ball in the cup for a bogey, while Kokrak hit his third shot to less than four feet from the hole. He knocked in the par putt toseal the win.
Spieth won at Colonial in 2016 when he shot 67 or less on all four days. Hehad rounds of 63-66-66 this time around before the Sunday collapse that included five bogeys and just two birdies.
