New York: Young American Aaron Wise chased down Australian Marc Leishman on Saturday to grab the co-lead at the AT&T Byron Nelson and set up a two-man showdown heading into the final round.

The 21-year-old Wise, who was a shot behind the leader entering the third round, shot a three-under-par 68 to tie Leishman at 17-under. He birdied the 16th and 17th holes in Dallas to briefly take solo control before making a bogey on the par-four 18th to drop back. Australian Matt Jones and American Kevin Na were four shots back at 13 under with Jimmy Walker and Brian Gay on 12 under.
