The final round of the John Deere Classic will begin Sunday much like Saturday’s third round. Troy Matteson’s name is atop the leaderboard and Steve Stricker, in pursuit of a four-peat, is three shots back. There are two key differences, however. One, the pressure is greater on a PGA TOUR Sunday. And two, Matteson will be paired with the three-time champion on Sunday. Six players were between Matteson and Stricker on the leaderboard after 36 holes but the congestion cleared up on Saturday as the aforementioned two were the only players in the final four pairings to shoot better than 2 under. Matteson started quickly, with two birdies in his first three holes, and added five more before the end of his round that resulted in a 5-under 66. Stricker birdied the first hole but couldn’t get much else going before making four consecutive birdies late in his round of 66. Both players bogeyed the 18th. Entering Sunday four shots back and playing in the penultimate grouping will be Zach Johnson and Brian Harman. Johnson, an eight-time PGA TOUR winner grew up in Cedar Rapids, Iowa, less than 100 miles from the course. Harman, a rookie ranked No. 97 in the FedExCup standings, is in search of his first victory -- and first top-10 finish -- on TOUR. In what promises to be an interesting Sunday at TPC Deere Run, 22 other golfers will enter Sunday’s final round at 10 under or better.
