I think people are able to define "platoon" as they please. It doesn't need to mean "Trevor Plouffe never sees a right-handed starting pitcher and his replacement never sees a lefty." Truth is, I don't think that kind of rigid definition necessarily exists. If the definition is "Twins should be more flexible in their lineup to try and have opposite hands hitting against pitchers", I think that's fine. On the other hand, the looser the definition, the more I think the Twins have done some of that, or at least where they've had the positional flexibility to do so in several areas, like right field. (They are less likely to do it in areas where they have a veteran, like first base or left field.) I guess if I was trying to measure it, I would do the following: - Find out the number of at-bats the Twins have had versus LHs and RHs (or maybe LH starting pitchers and RH starting pitchers). Find the percentage split. - For each Twins players, find out their same percentage split. Find which players vary the most from that. - Now doe something similar for a team that is considered a model of platooning, like the Rays. Do the percentages for the top 5 players vary as much as they do for the Twins? How about for another comparable poor team, like the Mariners?
