It really isn't that silly. Joe has been better at hitting for power, but his percentage of singles in 2013 is still 68.1%, and his triple slash for 2013 is virtually identical to his career averages. I hadn't said that Grace and Mauer were identical, but they are similar, close enough that Mauer would still be at best, a close call for the HOF as a 1st baseman. And their career wOBAs are pretty close- .364 vs. .377 for Mauer (and Mauer will probably fall closer to Grace's wOBA number as he ages). The main point is that there is a distinct dearth of run-producers on the roster. Putting Mauer at first and taking away one of the few positions where a proven run-producer can thrive without hurting the team much defensively will definitely hurt the Twins- I''m not sure what the exact formula would be, but I'm guessing that the Twins would have to significantly raise their team OBP, possibly by as much as 30 points, to offset the loss of yet another run producer in the lineup. As bad a year as Morneau had, by moving Mauer to 1st, you would be replacing Morneau's .323 wOBA with a catcher's wOBA like Hermann's (.281) or Doumit (.309). Signing a proven run producer Morales (.341), Loney (.339) or even a Swisher- (.336) type would help the Twins overall offense substantially. As for an alternative position, think of Joe's .377 wOBA at 3rd versus Plouffe's wOBA there of .306. The League Average wOBA at 1st is .334, at 3rd it's .314- the other Twins in-house options won't even cut close to those numbers. Think of a Morales (career average nearly .350 wOBA) or the Cuban first baseman potentially giving you a .350 wOBA or better number at First Base. That's how this team, in one set of simple steps can get incrementally much better going into 2014. Call Sano up in late June, platoon him at one of the positions or RF, and now you've added a 3rd step to significantly upgrading the run-producing potential.
