D.A. Points came back from a long rain delay and made four pars, the last one giving him a one-shot victory Sunday in the Houston Open and a second trip to the Masters.
Points rolled in a putt from just outside 12 feet on the final hole to polish off a 6-under 66 and avoid a playoff with Masters-bound Henrik Stenson and Billy Horschel.
Points' other PGA Tour win was the AT&T Pebble Beach National Pro-Am two years ago.
He began the year by missing the cut seven times in nine tournaments. But he kept his calm when he returned to Redstone Golf Club after a rain delay of nearly three hours.
"Thank you for staying," he said to the sparse gallery in the bleachers.
Stenson birdied his last two holes for a 66 before the storms rolled across the Houston area, and while he came up one shot short, he moved up to No. 42 in the world ranking to earn an invitation to the Masters, which begins April 11 at Augusta National.
Horschel was on the 18th tee when play was halted. After the delay he split the middle of the fairway, found the green and two-putted for par -- and a 66 -- to join Stenson in the clubhouse lead.
They waited around for a playoff that wasn't necessary when Points saved par on his last two holes.
"I've been having a really tough year," Points said. "To have a putt to win, you want that starting out every week. I would have liked for it to have been closer."
He finished at 16-under 272, and the win, worth $1,116,000, gives him another two-year tour exemption. His exemption from the Pebble Beach win would have expired this year.
Phil Mickelson opened his round with four straight birdies and was still in the picture until a three-putt double bogey on 14. He had a 68 and wound up six shots back.
Rory McIlroy closed out his week by making a 25-foot birdie putt for a 70 and a tie for 45th at 284. He'll play the Texas Open this week in San Antonio before heading to Augusta.
European Tour: Marcel Siem had a 2-under 70 to capture the Hassan II Trophy by three shots in Agadir, Morocco. He won $320,000 with a 17-under 217 total. But he'll miss the Masters with a ranking of 51 (top 50 get in).
