Houston — Charley Hoffman had a 2-under 70 for a one-shot lead over Jamie Lovemark at the Houston Open on Friday.

Lovemark was a former NCAA champion seeking his first PGA Tour title after having his career affected by back surgery. He was one of four players to shoot the day’s low score, 68, under conditions that worsened as the afternoon went on, which helped protect Hoffman from the field.

Dustin Johnson was among those chasing Hoffman, who opened with a 64 Thursday, but Johnson dropped back to 8 under with a bogey on 17, closing with a 71 after narrowly missing a 10-foot birdie putt on 18.

Johnson was in the last group to finish the round before darkness stopped play.

A 93-minute morning weather delay brought on by rain and lightning in the area ensured that 27 players will have to complete the second round Saturday morning.

Roberto Castro and Jamie Donaldson, are also at 8 under with three holes still to play, sharing third place with Johnson and Chez Reavie. Reavie shot 70 Friday to go with a first-round 66. Johnson and Castro had both opened at 65.

No Woods at Masters

Augusta, Ga. — Tiger Woods is going to Augusta National next week — to eat, not play.

Woods made official Friday night what most observers figured all along. Recovery from two back surgeries last year has not progressed to the point where it’s wise for him to tee it up at the Masters. It will be the second time in the last three years that Woods has not played the Masters.

Woods did say on his website that he has been hitting golf balls and training daily. But he still had no timetable for when he would return to competition.

He has said all along that he will not rush his return to golf. Woods turned 40 in January. His last victory was in August 2013.
