"Disappointing would have been going home after two days", he said.
Kisner had chances to recover from some of his misfortune, though he played the last three holes in 3 over.
With darkness falling, Jason Day parred the 18th to register a five-under 66 for a six-under-par total, two shots off the pace.
The PGA Championship has turned into a track meet.
Day was starting to look like the player who was No. 1 for so much of past year.
Day is a shot better than 2010 British Open victor Louis Oosthuizen (70, 67), Francesco Molinari (73, 64) and American Chris Stroud (14 holes), who is among 25 players that will complete their second rounds early Saturday.
The course was evacuated on account of unsafe weather conditions at 4.43 pm and about one hour 40 minutes play was lost.
Chris Stroud, victor of last week's Barracuda Championship and the last player to make the PGA field, was 5 under for the tournament and still had five holes to play in the second round when play was suspended because of darkness Friday.
'N.Korean missiles can reach Guam in 14 minutes'
The U.S. has two strategically significant bases on Guam, Andersen Air Force Base in the north and Naval Base Guam in the south. Resident Isaac Camacho, 19, says he feels Guam's relationship with the US mainland is "a little misunderstood on their part".
No one managed to post anything better than 67, and Olesen needed a long putt on the 18th hole for that. He is three strokes under par after rounds of 69 and 70 but knows he will be at least five strokes out of the lead starting his third round Saturday.
"I haven't hit it this well this whole summer - a lot of average finishes", Kisner said. "I just didn't make any putts". So I hit a 6-iron.
The idea is I have to get rid of negativity and also not be over enthusiastic in cases like back-to-back birdies or similar.
The Northern Irishman was one under for his round and level par overall through his first 10 holes on Friday, but a run of four bogeys in five holes threatened to derail his tournament. On seventh, he went into the rough and missed regulation and on eighth he missed an eight-footer for par and on ninth he missed from just inside 10 feet.
J.B. Holmes shot 67 on Saturday, moving to 1 over for the tournament.
The 28-year-old again displayed these characteristics of his recent form: streaky at times, but with the courage to pull himself back into the round.
Matsuyama fired seven birdies, including five in the back-nine, to charge ahead following a flawless second round. "I don't know, as low as I can go". But I was not getting defensive. "I mean, you can end up hitting right like Jason did today and then there is water on the left". He made the cut in only two of those.
Big names missing the cut included Justin Rose, Bubba Watson, Sergio Garcia and Danny Willett.
