Rollins came out quickly with three consecutive pars before catching fire. He posted back-to-back birdies from the fourth and again from the seventh to get to six-under.
At the par-five ninth hole, Rollins rolled in an eagle putt and followed with birdies on 10 and 11 to move to 10-under.
Rollins then parred five in a row from the 12th hole.
