PONTE VEDRA BEACH, Fla. (AP) So much for that Masters hangover for Jordan Spieth.

One month after the 20-year-old Texan tied for second at Augusta National, Spieth had another bogey-free round at The Players Championship on Friday and shot a 6-under 66 to trail Martin Kaymer by one shot going into the weekend.

Kaymer opened with a course record-tying 63 and followed with a solid round of 69. He was at 12-under 132.

Spieth was swinging so well he had a tap-in birdie on the 14th, the hardest hole at TPC Sawgrass on Friday. He had a chance to catch Kaymer until a three-putt par from just off the green on the par-5 16th.

Russell Henley had a 71 and was four shots behind. Jim Furyk was part of a large group at 6-under 138.
