Jhonattan Vegas reached 8 under, dropped back to 7 under on No. 17, then birdied No. 18 to take sole possession of the lead. The rookie from Venezuela now has company from another member of the 2011 rookie Class. With a birdie on the par-5 16th hole, this week’s Kodak Challenge hole, William McGirt has reached 8 under in what has been a bogey-free opening round thus far. McGirt, who qualified for the PGA TOUR Playoffs for the FedExCup in the last week of the Regular Season, has work to do to retain his full status on TOUR. He entered the Fall Series at No. 137 on the money list. Also moving up the leaderboard late in the afternoon was Charlie Wi. The South Korean birdied five consecutive holes on the back nine, his opening nine, and went on to post a 7-under 64, tied for the day’s second best score with early leader Nathan Green.
