New Zealand's Tim Wilkinson has fallen off the pace after a second round one-over 71 at the Byron Nelson Championship in Texas.
Wilkinson started the day in a share of second after a four-under 66 yesterday but slipped back in the field after three late bogeys moved him down to a tie for 17th.
Midway through the second day there was a seven-way tie for first place at six-under including last week's Players Championship winner Martin Kaymer and former Masters champion Mike Weir.
