Johnson, at eight-under, he trails leader Charley Hoffman by two and is tied for third with Chez Reavie, Roberto Castro and Jamie Donaldson, though the second round was suspended because of darkness with Castro and Donaldson on the 16th hole. Play will resume at 7:45 a.m. (CDT) on Saturday.

World No. 2 Jordan Spieth struggled, , meanwhile, shooting a one-over 73 including four bogeys. He trails Hoffman by six strokes, and is tied for 20th.
"I've just got to get more comfortable, find a setup position that I feel like is going to produce the correct start lines," said Spieth. "We still have five days or so [before the Masters] , so I've got a couple more competitive rounds and then a few more practice days."
Rickie Fowler shot a two-under 70, moving to five-under. His round featured six birdies and a double bogey. He is tied for 13th and five shots off the lead.
