AUGUSTA, Ga. (AP) — Jordan Spieth kept up his hot play on the PGA Tour with a brilliant opening round at the Masters, shooting an 8-under 64 Thursday for a two-stroke lead.

Spieth birdied eight of the first 14 holes, his shots so precise that he often had nothing more than tap-ins with the putter. He rolled in a 6-footer at the 12th, a 2-footer at the 13th, then nearly holed out from behind a tree along the 14th fairway, the ball striking the flagstick before settling about 2 feet away for another easy birdie.

The 21-year-old Texas went to the par-5 15th with a shot at the major championship scoring record, which is 63. But he muscled his second shot through the green, leading to his only bogey.

He finished up with a 20-foot birdie putt at the 18th.

Jason Day was 6 under with two holes to play. Charley Hoffman, Justin Rose and Ernie Els shot 67.
