If anything, he'll probably run a higher % when on, but he'll probably have less ABs, meaning less chances to run. In the end, I think the change in SBs will be minimal. Obviously, in terms of runs scored, it can't be good.
I don't think it'll last either. Willie has balls to move Reyes out of the leadoff spot...to bench Matsui...he's really showing that he will put the best team out on the field. He even swapped Piazza and Floyd in the order when Cliff started off hot. As long as Cam is hot, him batting leadoff is fine...but why isn't Wright batting 2nd or 5th? He doesn't want to put pressure on him, but I think he should be given a chance and not baby'd every step of the way. Certainly Marlon Anderson is not a better option.
