Robert Garrigus shot a 4-under 67 and shared the lead with Jimmy Walker and Brendon De Jonge among the early second-round starters at the AT&T National.
They finished with sweat pouring off their faces as temperatures climbed toward 100 (38 C).
Walker and De Jonge each had a 69 at Congressional.
Pat Perez, S. Y. Noh and Rod Pampling were one shot behind.
Tiger Woods made two key par saves and an eagle on his way to a 68, leaving him three shots behind.
Garrigus, meanwhile, must feel like taking up membership at Congressional. His 67 was his sixth straight round under par on the venerable Blue Course.
