FORT WORTH(CBSDFW.COM/AP) — Masters champion Jordan Spieth made a 20-foot birdie putt on the final hole with darkness falling Thursday, grabbing a share of the first-round lead in the rain-delayed Colonial.

Spieth just missed the green on his approach at the 18th hole, and putted from off the back right fringe. The closing birdie shortly after 8 p.m. put him atop the leaderboard with Kevin Na, Boo Weekley and Ryo Ishikawa.

After missing the cut at The Players Championship two weeks ago, the 21-year-old Spieth is playing the first of consecutive weeks at home in North Texas.

He had a great chance for a birdie on the par-3 16th, but his 4-foot try slid by the hole.

Play started three hours late Thursday after more than an inch of rain fell overnight at Hogan’s Alley.

Spieth is from Dallas and graduated from Jesuit College Preparatory School.
