Former Augusta State All-American Oliver Wilson recovered from a disastrous start to shoot 3-over-par 74 on Saturday.
Wilson bogeyed three of his first four holes but shot even par the rest of the way and is tied for 15th at 4-over 217.
He dropped shots to par on the first two holes, both par 4s, and gave back another shot on the par-4 fourth hole. He then made four consecutive pars before recording a birdie on the par-4 ninth to make the turn 2-over for the day.
Wilson suffered a double bogey on the par-4 12th before parring the next four holes. He then birdied the par-4 17th to get back to 3-over for the day.
Among the big movers in the third round were former U.S. Presidents Cup member Hunter Mahan (below), 2003 Masters Tournament champion Mike Weir and The Players Championship winner Sergio Garcia.
Mahan, a member of the 2007 U.S. Presidents Cup team, shot 2-under 69 to vault from a tie for 35th into a tie for sixth at 215.
