(Reuters) - Jordan Spieth charged into the lead with a stunning finish to his third round at the John Deere Classic on Saturday.
Masters and U.S. Open champion Spieth played the final three holes in four-under as he finished birdie, eagle, birdie at TPC Deere Run in Silvis, Illinois.
He holed out with a wedge from 107 yards at the par-five 17th, before running in a 15-foot birdie at the last for a 10-under-par 61.
Despite wayward driving down the stretch, Spieth used brilliant iron play and a hot putter for his PGA Tour career best score to move to a 17-under 196 total, two strokes ahead of New Zealand's Danny Lee, who shot a nine-under 62.
