I'm not disputing the platoon advantage (most hitters do better against opposite handed pitching, particularly LH hitters). I strongly believe in it. That's why I screamed bloody murder all winter over the Twins LH relief situation. I'm stating that, across MLB, "platoons" (two hitters sharing a position) have become so difficult to achieve, due to ever expanding pitching staffs, as to be virtually extinct. Teams still try to use the platoon advantage (without using a strict "platoon") to the best of their ability. But in the specific case of the Twins, there isn't much opportunity. You could try to use an Arcia/Park combo, but any short term OF injury that doesn't DL an outfielder makes that difficult/impossible. My guess is the Twins will be reluctant, at least initially, to use Park solely as a lefty masher. That's not what he was signed for, and I can understand wanting him to play every day, at least until he proves he can't do that. You might also sit Mauer sometimes if, say, Quentin is the fourth OFer, but the Twins are going to be pretty resistant to that idea as well, for obvious reasons.
