Padraig Harrington holds the clubhouse lead at the US PGA as the leaders get their final rounds underway.
Play in the third round resumed at 7am (12pm Irish time) and the fourth got under way at 8:40am (1:40pm Irish time), meaning the likes of Kevin Kisner and Harrington - who shot 65 on Saturday - had the chance to set a testing target well before the leaders teed off.
Harrington, who successfully defended his Open title in 2008 and won the US PGA a month later, birdied the third and picked up another shot on the fifth after hitting the pin with his approach to move to six under par.
Harrington was unable to make any further inroads and eventually had to settle for a 68 to finish six under par, with Justin Rose on four under after compiling the same score.
"They've put a lot of back pins out there and it's difficult to get close to them with these soft greens," Harrington said. "I didn't really give myself many chances and it was a little disappointing not to birdie the last, but such is life."
South Africa's Branden Grace had made the biggest early move up the leaderboard, birdies on the second, fourth and seventh lifting him to nine under par and just two off the lead.
American Jimmy Walker holds a one-shot lead after the third round of the weather-affected PGA Championship was finally completed.
Walker, who was one of 10 players unable to start their rounds on Saturday due to bad weather, carded a 68 at Baltusrol to finish 11 under par, a shot ahead of defending champion Jason Day.
Open champion Henrik Stenson, who is seeking a second major title in the space of three weeks following his victory at Royal Troon, was a shot further back alongside American Brooks Koepka after carding a third consecutive 67.
"I was struggling with my long game but the putter was behaving better so I'm happy to come in with that score," Stenson said.
"I think this 67 was better than the previous two so I just hope I can pick up some timing with my long game."
Walker was two over par for his round after 10 holes, but birdied four of the remaining eight to remain on track for a wire-to-wire victory which would complete a clean sweep of 2016 majors by first-time winners after Danny Willett, Dustin Johnson and Stenson.
"I made a couple of tentative swings early but just said, 'Trust it man, you're swinging good and keep the pedal down'," the 37-year-old said. "It's going to be an awesome afternoon."
Day, who is looking to become only the second player after Tiger Woods to successfully defend the US PGA since it became a strokeplay event in 1958, said: "We just didn't really know what was going on with the weather, but thankfully it let up and I'm glad we got the third round in.
"Patience was key and I played some good golf so looking forward to the fourth round."
The last five groups did not make it out onto the course on Saturday before an approaching thunderstorm forced play to be suspended at 2:15pm local time (7:15pm BST).
Persistent heavy rain then left parts of the course flooded before play was finally abandoned for the day shortly before 6pm local time (11pm BST).
