Guess who's in the lead again on the PGA Tour? Here's a hint: He won last week.
Jason Dufner leads after two rounds of the Crowne Plaza Invitational at Colonial. Dufner, who has won two of his last three PGA Tour starts, shot 6-under 64 to lead by two shots over 2010 Colonial winner Zach Johnson at 11 under par.
Defending champion David Toms missed the cut at Colonial for just the second time since 1998, shooting 5 over par.
