Jason Day putted for birdie on every hole Thursday and made half of them for a 9-under 63 that tied the course record and gave him a two-shot lead at The Players Championship.

Day played alongside Jordan Spieth, who was playing for the first time since losing a five-shot lead on the back nine at the Masters. Spieth had another poor finish at the TPC Sawgrass to post a 72 on a day that felt like hard work. He missed a 3-foot putt and took double bogey on his last hole. He was 3 over on his last five holes.

Masters champion Danny Willett opened with a 70.

Day only missed three greens — all of them just off the putting surface.
