Wilson had two birdies and eight pars through his first 10 holes but used an eagle on No. 11, a birdie on 14 and another eagle on the 15th hole to jump up the leader board. He faltered with a bogey on 18 but it was still good enough for the lead.
The 20-year-old Haig, playing the back nine first, opened his round Friday with a birdie and eagled the par 4 13th hole. He had two other birdies and a bogey before making the turn. He piled up four birdies and five pars on his second nine and tied the course record.
