Knost, McIlroy have low day

Colt Knost failed to birdie three of the par 5s and three-putted for bogey on the 18th hole, and he still tied the TPC Sawgrass course record at 9-under-par 63 on Friday.

Rory McIlroy shot a 64, his best round by two shots at the Players Championship, and was furious walking off the golf course.

Expectations soared as scores plunged on another day of moderate wind and soft greens before lightning delay suspended play in Ponte Vedra Beach, Fla.

Jonas Blixt and Alex Cejka set the target Friday morning, each posting 5-under 67 to share the lead among the early starters.

The world’s No. 1 player had three birdies in seven holes, and Day was threatening yet another record — the 14-under 130 for 36 holes by Greg Norman during his record performance in 1994.

Defending champion Rickie Fowler took another double bogey and left the course doubtful he would have a tee time on the weekend.

McIlroy slammed his putter into the bag.
