Troy Matteson didn't go nearly as low on Friday as he did in the first round of the John Deere Classic, but he will take a second-round 68 to put him at 13 under for two rounds.
"I'm fairly pleased," he said. "Like I said yesterday, if you told me I was going to get 13‑under after two rounds I would have taken it and not even teed it up."
Matteson admitted he felt the pressure to continue to be aggressive after making 10 birdies en route to 61 on Thursday.
"It's just really difficult to play the same every day. Your mind I think wants to do it that way, but a lot times if you shoot two low rounds you birdie in completely different holes," he said. "I knew today would be interesting because I might birdie or mess up different holes."
While it is difficult to go low for four days, Matteson embraces the shootout nature of the tournament.
"These tournaments where you got to shoot 20‑plus under to win are really fun because we get to make a lot birdies and see how the chips fall at the end of the day," he said. "It will be a very interesting finish."
