SILVIS, Ill. — Jeff Maggert’s decision to play in the John Deere Classic has worked out so far.

“I probably wasn’t 100 percent sure until Sunday afternoon,” Maggert said Friday.

Troy Matteson shot a 3-under-par 68 for a one-stroke lead over Maggert and 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 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.”

Maggert birdied four of his first six holes to start his bogey-free round, and kept it up. Not bad for someone who was going to take this week and next week off before playing the Canadian Open.

Now, he might have the option of playing in next week’s British Open.

The top finisher among the top five not otherwise eligible gets an exemption to next week’s major.

“I’m not really planning on going,” Maggert said. “Obviously if I were to win or something I might have to reconsider that. But I really need a week off in my game.”

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.
