HUMBLE — D.A. Points came back from a long rain delay and made four pars, the last one giving him a one-shot victory in the Houston Open and a trip to the Masters.With a putter he once borrowed from his mother and never returned, Points rolled in a putt from just outside 12 feet on the final hole to polish off a 6-under 66 and avoid a sudden-death playoff with Masters-bound Henrik Stenson and Billy Horschel.It was quite a turnaround for Points, whose only other PGA Tour win was at Pebble Beach two years ago with actor Bill Murray along for the laughs.He started the year by missing the cut seven times in nine tournaments. He arrived at Redstone Golf Club having not broken 70 in his past nine rounds. But he stayed in the hunt after opening with a 64, and he kept his calm when he returned to the golf course after a rain delay of nearly three hours.“Thank you for staying,” Points said to the sparse gallery in the bleachers as he walked off the green.Stenson birdied his last two holes for a 66 before the storms rolled across Houston, 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.Horschel was on the 18th tee when play was halted, and then had to wait some more for his turn to hit on the tough driving hole. He split the middle, found the green and two-putted for par 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.”Points picked up his final birdie on the par-5 13th when the hole got in the way of his chip and kept the ball from running well past. It instead stopped 3 feet away.Briefly • European Tour: Marcel Siem of Germany shot a 2-under 70 to win the Hassan II Trophy by three strokes in Agadir, Morocco. He earned his third European Tour title with a 17-under 217. • Asian Tour: Australian Scott Hend won the inaugural Chiangmai Golf Classic after a final-round 64 to beat South African Bryce Easton by three strokes.
