Canada's Hadwin finishes tied for 4th at the Valero Texas Open

J.J. Spaun won his first PGA Tour event — and his first trip to the Masters — by firing a final-round 69 at the Valero Texas Open on Sunday.

In his 147th PGA Tour start, Spaun survived a double-bogey start to his round by recording five birdies with no bogeys to finish at 13-under at TPC San Antonio. It gave him a two-shot margin over Matt Kuchar (69) and Matt Jones (66).

Adam Hadwin of Abbotsford, B.C. shot a closing-round 67 to finish tied for fourth at 10-under alongside Beau Hossler (72), Charles Howell III (69) and Troy Merritt (69).

The 31-year-old Spaun closed with four straight pars, and no one could close in on him. His previous best finish on tour was runner-up in 2018 at the RSM Classic.

Jones missed a 3-foot par putt on the 16th, birdied the 17th and missed a 14-foot birdie putt on the final hole.

Kuchar needed a birdie on the final hole and Spaun to make bogey to force a playoff. Spaun found trouble off the tee in the left rough, but Kuchar's second shot went into the water. Spaun reached the green of the par-5 finishing hole in three and his final putt was less than two feet.

It was a missed opportunity to get back to the Masters for Kuchar and Brandt Snedeker, who shared the lead after the first two holes Sunday. Between them, they have 26 Masters appearances, seven top 10s and each has a top-3 finish.

Snedeker finished tied for 18th after a 75.

Spaun's double-bogey final round start before getting the victory is so rare that the last time it happened on tour came in 2008, when Tiger Woods won the U.S. Open victory (and Woods needed a playoff the following day).

Spaun took the lead with a birdie after nailing his approach into the 11th to three feet
