Walker was poised to overtake Weekley but had two late bogeys.
Compton couldn’t grind out the birdies that dominated his first round, when he tied Matt Every for the lead at 7 under.
Still, Compton, looking to solidify a future either on the PGA Tour or the Nationwide circuit, put himself in good position for the weekend. His highest finish is 30th at the Arnold Palmer Invitational.
“I was just frustrated because three birdies out here is not acceptable,” Compton said. “I need to be a little better keeping it below the hole.”
Every made double bogey at the par-5 17th, shot 72 and was nine strokes back.
Carl Pettersson, last week’s Canadian Open winner who barely made the cut in that tournament, shot 64 Friday and was at 5 under, three strokes above the cut line.
