Jordan Spieth backs up tired 74 with stunning 62 at Harbour Town

Oh, come on.

A day after Masters champion Jordan Spieth looked deservedly tired and sluggish in shooting 3-over 74 in the first round of the RBC Heritage, the 21-year-old came back early on Friday and shot 9-under 62 at Harbour Town Golf Links to get into contention on Hilton Head Island, S.C.

Spieth made nine birdies in the round, not dropping a shot. The Texan birdied the 10th hole, his first of the day, then made eight birdies in the final 14 holes of the round to go from the cut line to the first page of the leaderboard.

On the back nine, Spieth made five birdies, with four of them coming on putts of 7 feet or less. At the par-4 eighth, his 17th hole of the day, Spieth made a 41-foot chip for birdie.

The round ties his PGA Tour career low.

Spieth now has the afternoon session to wait to see the final leading number, but he now has a chance to become the first player to win the Masters and Heritage in back-to-back weeks since Bernhard Langer in 1985.
