PGA Championship: Kevin Kisner holds early second-round lead

CHARLOTTE, N.C. -- Kevin Kisner stretched his lead by posting a 4-under-par 67 in Friday's second round at the PGA Championship at Quail Hollow Club.

He was the leader by four shots when golfers with morning tee times finished. Another wave of golfers teed off later on a steamy day.

Kisner, who shared the top spot entering the day with a first-round 67, sits at 8-under through two rounds.

Kisner continued what had been a late surge Thursday by posting birdies on two of the first three holes in the second round, which he began on the back nine. Then on No. 7, he posted an eagle for the only hole he didn't post a par on that side.

Rickie Fowler stayed in contention with a 70, moving to 3-under for the tournament.

D.A. Points appeared to be Kisner's biggest threat until double-bogeys on Nos. 16 and 17 pushed him to 1-under for the tournament. Points ended up with 73 in the round.

First-round co-leader Thorbjorn Olesen had an afternoon tee time Friday.

Phil Mickelson, who followed Thursday's 79 with a 74, is lined up to miss the cut in the PGA Championship for the first time in 22 years. Mickelson didn't have a birdie until his 31st hole of the tournament.
