Beau Hossler was steady while better-known players faltered down the stretch Friday at the PGA Tour Houston Open, leaving him with a one-shot lead heading into the weekend in Humble, Texas.
Hossler, 23, shot 4-under-par 68 for a two-day total of 11-under 133, good enough for the second 36-hole lead of his rookie season. He shared the lead with Dustin Johnson at the halfway mark at Pebble Beach before falling out of contention.
Rickie Fowler was tied with Hossler before he hooked his drive into the water on the tough par-4 18th, leading to bogey.
Jordan Spieth's putter heated up before his momentum stalled with a missed 3-footer on the 16th hole. He shot 67 and was two shots back.
Phil Mickelson took the biggest step backward on 18. He was bogey-free for 17 holes and 8 under for the tournament before he found the water twice and made triple bogey.
• Michelle Wie fought through vertigo, Lexi Thompson battled a balky putter — and Pernilla Lindberg and Sung Hyun Park quietly broke away at the ANA Inspiration in Rancho Mirage, Calif.
Park and Lindberg shared the lead at a tournament-record 12-under 132, three strokes ahead of Jessica Korda after two rounds in hot and mostly calm conditions at Mission Hills in the LPGA's first major of the year.
Thompson was 4 under after an even-par 72, undone by a series of short missed putts — one year after a rules violation cost her four strokes in regulation in an eventual playoff loss.
