SAN ANTONIO (AP) South African Branden Grace had a 6-under 66 and leads by a stroke after the opening round of the Valero Texas Open on Thursday.
Grace had a season-best 11th-place finish last week in defense of his RBC Heritage title. He leads the 5-under 67s of Steven Alker, Stewart Cink, John Huh and Will MacKenzie at TPC San Antonio. Alker, a journeyman New Zealander who played in the final group of the day, birdied the final three holes.
There are 13 players packed two shots back at 4 under. That includes 2010 U.S. Open champion Graham McDowell and 2016 U.S. Ryder Cup member Brooks Koepka.
