Rickie Fowler woke at 5am Saturday and played three holes in the PGA Tour event at Mayakoba but it was enough to get him a three-way share of the 36-hole lead going into a marathon finish in Mexico.
Fowler and Patrick Rodgers had to wait out a five-hour rain delay just to resume their second round Saturday.
Fowler saved par from a bunker on the 18th hole for a four-under 67.
Rodgers finally make his first bogey of the tournament on his 17th hole to settle for a 65.
They shared the lead at 10-under 132 along with Patton Kizzire, who hasn't hit a shot since his 70 on Friday.
Matt Jones had four birdies in an unblemished round of 67 to join Geoff Ogilvy (71) at three under as the best-placed Australians.
Greg Chalmers had an even=par 71 to be a shot further back in a toe for 51st while Aaron Baddeley made the cut on the number after a three-under 68.
The last three groups didn't have enough light at El Camaleon Golf Club to even start the third round, leaving them a 36-hole finish on Sunday.
But that's only if the weather at this rain-plagued event allows.
More thunderstorms, with heavy downpours, were in the forecast for the next two days.
"We deal with weather every once in a while on the PGA Tour, around the world, really," Fowler said.
"You kind of just learn to play when you get to play, relax when you get to relax. Rest when you can, tee it up when you can."
With the forecast, there was no guarantee of getting in 72 holes.
Players will be allowed to lift, clean and place their golf balls through the green for Sunday.
Fowler hasn't played since October 1 at the Presidents Cup.
"I'm very happy, coming from basically five weeks of very little golf played," Fowler said.
