Masters champion Jordan Spieth made a 20-foot birdie putt with darkness falling for a 6-under 64 and a share of the first-round lead Thursday 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.

Spieth opened his bogey-free round with a 25-foot birdie putt at No. 1, then started the back nine with another a 22-footer at No. 10. He had a great chance for another birdie on the par-3 16th, but his 4-foot try slid by the hole.
