Jimmy Walker made himself right at home on the Texas Open leaderboard. Walker won his hometown event Sunday to become the first two-time winner this season on the PGA Tour, beating fellow Texan Jordan Spieth by four strokes. ”(Spieth) really made me fight hard,” Walker said. ”He kept hitting it close, and I had to keep making putts.” Walker made birdie putts of 15 feet at No. 16 and 17 feet at the 17th in a 2-under 70 that left him at 11-under 277 at TPC San Antonio, a 35-minute drive from his home.
