Troy Matteson is showing no signs of feeling pressure early in Round 3. The 36-hole leader two-putted from inside 10 feet for birdie on the par-5 second, then made a 9-foot birdie putt on No. 3 to reach 15 under and increase his lead to two at TPC Deere Run. Matteson's best finish thus far in 2012 is a tie for 26th at The Honda Classic. He projects to move to 41st in the FedExCup standings with a victory. Giving chase is Brian Harman, who is 1 under through four holes today and 13 under for the week. Another shot back are Jamie Lovemark, who posted an early 64 today, Billy Hurley III, John Senden, Robert Garrigus, Ricky Barnes and J.J. Henry. Steve Stricker, who is looking for a fourth consecutive victory at the John Deere Classic, is another shot back at 11 under.
