Patrick Cantlay finished his long day with some of his best golf, running off three straight birdies to close out a five-under 67 and share the lead in the rain-delayed and darkness-suspended Memorial.
He arrived at Muirfield Village before dawn. He finished when it was time for dinner. And except for a few inevitable mistakes, he was solid in the 33 holes he faced.
"We're out there for such a long time today that you could fall asleep at the wheel a little bit," said Cantlay, who won the Memorial two years ago. "So being cognisant of that and checking in with yourself - are you as focused as you can be? - I think is the key."
Cantlay was at eight-under 136 on the refurbished Muirfield Village, where the rough is thicker and denser than usual and the rain that washed out nearly half of the opening round didn't help.
Scottie Scheffler recovered from three bogeys in his opening four holes to scratch out a 71 and was at six-under 130 among those who completed the second round.
They all had long days, having to finish most of the first round in the morning and 18 holes in the afternoon, with only about 30 minutes in between.
Collin Morikawa and Jon Rahm, both winners at Muirfield Village last year in different tournaments held in consecutive weeks, were among those who had to return Saturday morning.
Rahm was tied for the lead at eight under through 13 holes, making a two-foot birdie putt before darkness halted play. Morikawa was right there with him until a triple bogey on the 12th hole.
The tournament should be back on track in time for the final round Sunday.
Jordan Spieth had reason to wonder if his long day would lead to a short week. He had a hard time keeping his tee shots in play, meaning hacking out and trying to save par with his wedges.
He was five over for his opening round when he fired an eight-iron into eight feet for birdie and a 76.
He followed that with a 67 to reach one-under 143. That was more than enough to make the cut and to at least still be in the mix.
Spieth played with Cantlay and Bryson DeChambeau, and it didn't lack for excitement. Cantlay was playing great. DeChambeau was bothered by a few spectators calling him, "Brooksy," a reference to his spat with Brooks Koepka, who isn't even at the Memorial.
Some spectators were removed. DeChambeau laughed it off later by saying it was "flattering."
DeChambeau also was at 143 with three double bogeys on his card.
Faring much better was Australian Lucas Herbert.
The 25-year-old from Victoria is tied for eighth after a three-under 69 moved him up 23 places, following his opening 71.
Herbert, who is looking for his second win after taking out the Dubai Desert Classic, mixed five birdies with two bogeys.
He is two ahead of compatriot Adam Scott, who followed up on his disappointing first-round 74 with a four-under 68 on Friday.
