A four-man rotation where starters throw 110 pitches might have nothing in common with one where they only throw 65.
From that article, for those who skip it: "Surprisingly, though, the results came out the same. There was no indication that pitchers did better or worse based on how many days of rest they got. What was significant was the number of pitches that the pitcher had thrown in his previous start. Longer outings made for slightly less effective pitchers (more walks, more hits, fewer outs in play). It’s something we’ve seen before. Using more modern data, I found that a pitcher who threw 140 pitches might expect to perform slightly worse than expected in his next start, and that the effect was gone by the second start."
True. They're also going to be giving Tampa Bay's starters four days rest instead of the three days rest that old school four man rotations use to.
