Jason Day continued to treat TPC Sawgrass as his own personal playground Friday, taking a three-shot lead in a Players Championship curtailed by darkness.
What it means: World No. 1 Day needs only to par in to equal the tournament's 36-hole record of 14 under. He already had hit his drive into the fairway at the par-4 15th when the horn blew, and his group elected to mark their balls and finish the hole Saturday morning.
Round of the day: Colt Knost shot a 9-under 63 that tied the course record. Only a missed 4-foot par putt kept him from a record 62. Knost birdied No. 3 and Nos. 5-8 to make the turn in 31, then added circles at Nos. 11 and 12, 14 and 15 and 17 before making his one slipup at 18.
Best of the rest: Rory McIlroy followed his lackluster opening-round 72 with an 8-under 64 that thrust him into contention. Starting on the back nine, McIlroy birdied his first four holes and five of his first six. He added an eagle on his seventh hole and made the turn in 29. He cooled off on the front, making only two birdies. And he bogeyed the par-5 ninth hole.
Biggest disappointment: Defending champion Rickie Fowler is at 1 under after a 71, which is one stroke outside the projected cut line. Unless that line moves, Fowler will become the first defending champion to miss the cut since K.J. Choi in 2012. Jordan Spieth is also at 1 under, but he has four holes left to play.
Shot of the day: Jarring a pitching wedge from 147 yards, Will Wilcox became only the sixth player to make a hole-in-one at the 17th hole, and the first since Miguel Angel Jimenez did it in 2002.
Quote of the day: "I get pumped up. I finished 15th in New Orleans and acted like I just won the Masters. If I finish 38th this week I'll party, too." - Wilcox
