Poston takes 3-shot lead heading into final round at John Deere Classic

J.T. Poston made up for two back-nine bogeys with an eagle on the par-5 17th, shooting a 4-under 67 on Saturday to take a three-stroke lead into the final round of the John Deere Classic.

Trying to complete a wire-to-wire victory after tying for second last week in the Travelers Championship in Connecticut, Poston made a 13 1/2-foot eagle putt on 17.

"That was huge kind of going into tomorrow," Poston said about the eagle. "I wasn't quite as sharp today off the tee and had to play a little defensive into some of the greens. Nice to put two good swings on there and make that putt to kind of capitalize and get some ground back that I had lost."

Playing partner Denny McCarthy birdied the final two holes for a 66 to join Scott Stallings (64) and Emiliano Grillo (65) at 16 under.

"Was nice to finish that way," McCarthy said. "Nice to make a putt on 18. Nice to see something go in going into tomorrow. It's a good feeling to kind of feel like I got something out of round, birdieing the last two."

Michael Gligic (68) of Burlington, Ont., sits in a tie for 10th at 12 under, while Adam Svensson (68) of Surrey, B.C., is a shot back.

Adam Hadwin and Nick Taylor, both of Abbotsford, B.C., David Hearn of Brantford, Ont., and Roger Sloan of Merritt, B.C., all missed Friday's cut.

Poston opened with rounds of 62 and 65 to take a four-stroke lead, then played the front nine in 3 under Saturday with birdies on Nos. 2, 5 and 8. He dropped a stroke on the par-3 12th, birdied the par-4 14th and bogeyed the par-4 15th before making the big putt on 17.

From Hickory, North Carolina, the 29-year-old Poston won the 2019 Wyndham Championship for his lone PGA Tour title.

Stalling birdied Nos. 15-17.

"Look forward to the opportunity." Stallings
