"I really played well," Woods said. "The score is not indicative of quite how well I played."
Everyone within 10 shots of the lead will be back on Saturday.
That includes a youngster who's on quite a field trip.
Guan just needs to speed things up a bit.
Fred Ridley, the club's competition committee chairman, said Guan's threesome was first warned for being too far behind the group ahead of them at the 10th hole. The teenager went on the clock two holes later — an official imposes a 40-second time limit to play a stroke — and gave Guan his first warning at No. 13.
"In keeping with the applicable rules, he was penalized following his second shot on the 17th hole when he again exceeded the 40-second time limit by a considerable margin," Ridley said in a statement.
That turned what would have been a par into a bogey. Guan finished at 75 and 148 overall.
"I respect the decision," Guan said. "This is what they can do."
The last player to be penalized for slow play at a major was Gregory Bourdy at the 2010 PGA Championship at Whistling Straits. No one could find a record of anyone getting penalized in such a way at Augusta National.
"I know the rules pretty good," Guan said. "But I think my routine was pretty good, too. Just the wind changed. The weather, it was not a good day."
A rainy morning turned into a sunny, blustery afternoon, which sent scores much higher than they were in the opening round. Guan said it took him longer to judge distances and pick clubs because of the wind.
Leishman, a 29-year-old Australian with only one PGA Tour victory, kept up his solid play in the tough conditions, while others skidded down the board.
