SILVIS, Ill. — Troy Matteson shot a 3-under-par 68 for a one-stroke lead over Jeff Maggert and Savannah's Brian Harman after two rounds of the John Deere Classic on Friday.
    Matteson was at 13-under 129.
    Maggert's bogey-free round of 9-under 62 moved him from 39th place after the first round to a tie for second. He birdied half the holes at TPC Deere Run, including five of his last nine.
    Harman, a former standout at Savannah Christian and the University of Georgia, had a second straight 65, the last two of his seven birdies coming after a 48-minute thunderstorm delay.
    Matteson bogeyed the par-4 18th after getting four birdies in the first 17 holes.
    Maggert one-putted 10 greens and saved par twice en route to matching his career-low round. He finished by making a 13-foot birdie putt on the par-4 ninth hole.
    "I saw the putts better today," Maggert said. "But I'm going to be aggressive tomorrow. I feel I need another really low round Saturday or Sunday, 7- or 8-under, to be in contention. The last few years, guys have really been lighting it up here."
    Including Maggert's 62 and Matteson's first-round 61, there have been eight rounds of 62 or lower at Deere Run in the past five years, and 11 since the tournament moved to the course in 2000. The best effort was Paul Goydos' Tour-record-tying 59 two years ago.
    J.J. Henry, Gary Christian, Robert Garrigus and Ricky Barnes are tied for fourth at 11-under 131.
    A trio of players are at 10-under 132, including three-time defending champion Steve Stricker, whose 4-under 67 placed him within striking distance with 36 holes to play. Tommy Biershenk and two-time U.S. Open champion Lee Janzen are also at 132.
    Zach Johnson shot 6-under 65 and was at 9-under 133.
    Harman, in the next-to-last group, finished off his 65 by chipping in for birdie on the ninth hole.
