Bo Van Pelt moved to 11-under par to take a one-shot lead through eight holes of his third round at the Shell Houston Open just before play was suspended Saturday because of darkness.
Fred Couples, Paul Casey, Colt Knost and Tommy Armour III were all at 10 under when the horns sounded at 7:34 p.m. The players will resume the round early Sunday, then immediately tee off for the final 18.
Van Pelt, winless in eight-plus years on the PGA Tour, shot a 67 in the second round, then birdied three of the first seven holes in his third round.
Knost, playing with Van Pelt, was leading at 11 under until a three-putt bogey at the par-5 eight. Van Pelt hit a pitch to 3 feet and sank the birdie putt to switch places with Knost and take the outright lead.
