Matteson one ahead but Maggert lurking

Troy Matteson leads by one shot at the halfway stage of the John Deere Classic but Jeff Maggert's 62 has put him in contention.

Matteson carded a career-best 61 on Thursday to lead the field by three shots after the first 18 holes and he backed that up with a three-under-par 68 on Friday to sit on 13-under-par with 36 holes to play.
But the pack are closing as Maggert joined Brian Harman in second place after a nine-under 62, while Harmon's 65 means he is in great shape to challenge over the weekend.
Four players are a further shot back, with Americans JJ Henry, Ricky Barnes and Robert Garrigus joining England's Gary Christian on -11.
Steve Stricker has won the tournament for the past three years and he is, once again, near the top of the leaderboard, adding a 67 to his opening 65 to sit on -10 and a share of eighth place with Tommy Biershenk and Lee Janzen.
But Matteson is the man they will all have to catch over the weekend in Illinois and the 32-year-old Florida-born star admitted that it was difficult to try and replicate his first-round heroics on Friday.
"It's just always tough when you shoot a low one to come to the golf course the next day," he said. "I got here early. You get a little out of sync because you're anxious to get out there and play and see what you do. But, you know, all in all I felt pretty good with what we did today."
Stricker is looking to join just a handful of players who have won an event four years in a row and the 45-year-old was pleased with the way he bounced back after dropping an early shot.
"Kind of wasn't the start I was looking for," he told the PGA Tour website. "I was hoping to get a birdie before I got a bogey - or no bogeys at all.
"But I hung in there. I was patient and hit some good shots. I made a nice long putt at 13 and birdied 14, so I righted the ship pretty quickly and got her going in the right direction."
England's Brian Davis carded a second-round 65 to finish on three-under-par but, for the second consecutive week, missed the cut by just one shot.
