Lead too big?

Tiger Woods shot a 5-under 67 on Saturday and leads Jim Furyk by six shots and Zach Johnson by seven. Woods has the largest 54-hole lead in the Target World Challenge history.
``Seven shots is too much behind Tiger Woods, just because of what he’s done,’’ Johnson said. ``Freakish things can happen. Anything is possible. But the guy, if he’s in the lead, the gap seems to go the other way.’’
Woods has won the tournament three times but always came from behind to win.
