Grace up 1 in Texas — South African Branden Grace shot a 6-under-par 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. Two weeks ago, Grace was over par but still survived the cut at the Masters. He played the weekend at Augusta in 3 under, and his best scorecard last week at Hilton Head was 68. The 66 on Thursday was his best round since Hawaii in January. “That’s the one round I was waiting for,” Grace said. “I’ve been shooting the 69s and 70s, but not getting that one low round. This is nice.”
