Justin Rose had to settle for a share of the lead at the end of day two of the BMW Championship at Cog Hill, Illinois.
The Englishman started the day with a two-shot lead, but ended on 11-under with American Mark Wilson.
Webb Simpson is in third place on nine-under, while Australia's John Senden is one shot further back in fourth.
World number one Luke Donald endured a difficult opening round, but he hit a 66 to move to one-under going into the weekend.
