Brendan Steele was eight-under par through 13 holes and leading in the first round of the Valero Texas Open on the AT&T Oaks Course at TPC San Antonio when play was suspended by darkness for the day. Steele's only PGA Tour victory came in this event in 2011.
Play was delayed early Thursday morning because of heavy rains and began shortly after noon, a 3 ½-hour delay. When darkness haulted play around 8 p.m. (CDT), 78 players had yet to complete their first round.
Charley Hoffman trails Steele by two strokes after shooting a six-under par 66. Stuart Appleby and Peter Malnati are tied for third, three shots off the lead at five-under.
Zach Johnson, a two-time winner of this event, finished at three-under 69 and five shots off the lead.
"It's amazing how well the sun can dry this place up," said Johnson. "We had a few mud balls. Jimmy [Walker] had a terrible mud ball on the eighth hole, 17. What do you do? That's golf. But hats off to the greens staff. Everyone that's in charge of this golf course did a great job."
Bryson DeChambeau, who finished T4 in his first professional tournament at RBC Heritage last week, shot a two-over 74 and is tied for 117th.
Phil Mickelson, still looking for his first finish inside the top 30 at this tournament, was one over through the 14 holes that he played.
