(AP) -- Troy Matteson scored 10 birdies Thursday en route to a bogey-free round of 10-under 61 for a three-stroke stroke lead after one round of the John Deere Classic.

Matteson, a two-time winner on the PGA Tour, birdied five holes on each nine of the TPC Deere Run to surpass the 7-under 64 of second place Ricky Barnes.

Matteson started by making birdies on three of his first four holes and finished with birdies on four of his first five.

He nearly holed out from a bunker on the par-4 ninth for a 60, but settled for par.

Barnes, out in the second group of the day, birdied all three par-5s and two of the four par-3s.
