May 19 (Reuters) - 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.
Wise is hunting his first PGA Tour win after tying for second in the Wells Fargo Championship two weeks ago.
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.
Leishman grabbed control of the tournament in the opening round with a 10-under-par 61 and has been steady since, making just two bogeys over his last two rounds at the links-style Trinity Forest, the tournament’s new home.
Leishman, 34, won twice on the PGA Tour a year ago and will be looking for his first triumph of this season.
Hometown favourite and three-times major champion Jordan Spieth failed to push his way into contention, settling for a level-par 71 that left him well back at seven under.
