Tommy Biershenk, Y.E. Yang and three-time defending champion Steve Stricker have joined the group in double digits under par during the second round of the John Deere Classic.
Interestingly, Biershenk has only made one par in his first 11 holes and has moved into a tie for second with J.J. Henry, two strokes off Troy Matteson's lead. He's 6 under for the day and 11 under for the tournament.
Biershenk started on the back nine and birdied his first two holes before making the lonely par. Two more birdies were followed by a bogey, then two more birdies and another bogey as Biershenk made the turn in 32. He's birdied his first two holes on the front, as well.
Yang is 7 under through 17 holes while Stricker, who has won the last three events at TPC Deere Run and is playing the opposite side as the former PGA champ, is 4 under for the day. Both are 10 under, three behind Matteson who has finished with a 68.
