Hideki Matsuyama owns a share of the PGA Championship lead going into the weekend after a bogey-free 64 in a suspended second round Friday.
Matsuyama rattled off four consecutive birdies from the 12th hole at Quail Hollow, where play was halted by a thunderstorm for almost two hours. The round was later stopped by darkness, and the final 25 players will complete their rounds on Saturday.
Matsuyama, who had seven birdies in all, is tied at the top of the leaderboard with Kevin Kisner at 8-under 134. They are two shots ahead of Jason Day, the 2015 champion, in third with a party of three trailing a shot further back. One of the trio at 5-under, Chris Stroud, had his second round stopped at the 13th.
For the first time in his career, Matsuyama leads at a major after two rounds.
"I think I'm playing well. I'm definitely picking it up," the world No. 3 said. "I was tired so I took (the rain delay) as a nice break."
"It makes me nervous being in the lead after two days at a major, but I'm really looking forward to the next two days. I want to win it."
Coming off his second World Golf Championships victory last week after shooting a record-tying final-day 61 at the Bridgestone Invitational, Matsuyama credited his improved putting for Friday's score.
Matsuyama had a total of 23 putts, eight fewer than he did in the first round.
"I don't know if it's the new putter I'm using, but the greens here are really fast and I'm not expecting my putts to fall. Maybe that kind of relaxed mindset is working out for the better," Matsuyama said.
"I hope I can be back (at the press conference) after the final round."
Fellow Japanese Hideto Tanihara shot a 75 to sit in 61st at 4-over but he is likely to survive into the weekend with the projected cut line at 5-over. Satoshi Kodaira sits 70th at 5-over and Yuta Ikeda missed the cut after a 79 on Friday leaving him at 9-over.
