Curtis Granderson was a perfect table setter, with his numerous doubles and triples complementing the singles hitting Placido Polanco very well. Moving him down in the order, assuming 18 PA's per spot in the lineup, will mean that Granderson will bat roughly 72 fewer times than he would batting leadoff. Using PECOTA's projections, that's somewhere between 2 and 3 homeruns lost and between 26 and 27 total bases lost. Simply put, having Curtis Granderson batting leadoff allows the Tigers to maximize the amount of times one of their best hitters comes to the plate. Moving him down in the lineup is a bad idea. If the idea is to use Anderson as some kind of table setter, batting him ninth would make a ton of sense, if not for the platoon disadvantage created by having two lefties back to back.
However, it's possible that today's spring lineup is nothing to get worried about and it's just an attempt to allow Anderson to bat as often as possible in front of the Tigers' staff. Let's hope that's the case.
