Lineup optimization really doesn't make much difference, we're talking about maybe a couple runs over the course of the season. For me, it's just frustrating that Gibbons doesn't realize that Colabello is fool's gold and has been RTTMing for awhile now. I would rather bat Martin leadoff and Tulo 4th.
Of course, the reasoning for not batting Martin leadoff is probably as simple as Gibby wanting to give him some time to take his catching equipment off after the Top of the 1st, or something like that which only matters in the 1st inning.
