Tiger Woods, Carl Pettersson and Vijay Singh are in a three-way tie for the lead at the 2012 PGA Championship at four-under par. Course conditions were tougher on the golfers in the second round, which made the 69 that Singh shot, as well as Woods' 71, impressive scores. Pettersson, who led the field after day one, shot a 74.
