SAN ANTONIO -- Branden Grace of South Africa fashioned seven birdies in his first 14 holes and settled for a 6-under-par 66 to establish a one-shot lead on Thursday after the morning wave of the first round of the Valero Texas Open.
Will MacKenzie and John Huh were a shot back after 67s in the morning wave played under mostly benign conditions at the TPC San Antonio Oaks Course.
