Troy Matteson shot a 5-under 66 Saturday to take a three-shot lead into the final round at the John Deere Classic.
Steve Stricker, who also shot a 66, sits in second place at 15 under in his quest for a fourth straight tournament title. Stricker birdied four straight holes beginning at the 14th, but bogeyed the par-4 18th, stubbing a chip shot and missing a 15-footer for par.
Both Matteson and Stricker bogeyed the last hole, setting up their final-round pairing together at TPC Deere Run, where Stricker, a Wisconsin native who was an all-American at Illinois, has become a local favorite by winning the last three years.
Former Masters champion Zach Johnson also carded a 66 to climb into contention at 14 under, along with left-hander Brian Harman.
