Justin Leonard posted a two-under 70 on Saturday and was joined atop the leaderboard by Kevin Chappell after three rounds of the Children's Miracle Network Hospitals Classic.
Chappell fired a six-under 66 to match Leonard at 14-under-par 202. Leonard, who holed out three times on the front nine for birdie, will go for his 13th PGA Tour title on Sunday, while Chappell will be going for his first tour win.
Bio Kim, who shared the second-round lead with Leonard and Henrik Stenson, managed a one-under 71 to drop into third place at minus-13.
Stenson holed an 11-foot par putt at the last to shoot 72. He shares fourth place at 12-under-par 204 with Nick O'Hern (70).
After play rotated between the Palm Course and Magnolia Course at Disney, the third round was contested on the Magnolia Course.
With players battling to get inside the top 125 on the money list, there was an even bigger battle at the top of that list.
Money-leader Webb Simpson was one-over par through nine holes and trailed No. 2 Luke Donald by three strokes. The duo, who was playing together for the third straight day, had much different back nines.
Simpson birdied four of six holes from the 10th en route to a three-under 69. Donald faltered to a double-bogey after driving it in the water on the par- five 14th.
After that poor drive, Donald three-putted for his double-bogey. That ended a streak of 483 holes without a three-putt for Donald. He also bogeyed 16, but closed a round of two-under 70 with a birdie at the last.
Simpson shares ninth at 10-under-par 206, while Donald is one back at minus- nine. Donald needed a two-way tie for second or better to have any chance at passing Simpson for the money title.
