The PGA Tour heads to San Antonio this week for the Valero Texas Open. Here are three featured groups to watch at TPC San Antonio:
8:40 a.m. ET off 10 tee Thursday/1:50 off 1 tee Friday: Zach Johnson, Jimmy Walker and Justin Leonard
Johnson, a two-time winner of this event when it was held at LaCantera, has finished inside the top 20 in four of his five career starts. He was in the mix last week at the RBC Heritage before a closing 77 sent him to a tie for 33rd.
