The fallout

What Joe Mauer's move to first base means to the Twins:

Clears logjam at DH: With Mauer at first and Ryan Doumit traded to Atlanta, space is cleared for an everyday DH, presumably Josh Willingham.

Creates need at catcher: Rookie Josmil Pinto is projected as Mauer's eventual successor, and free agent Kurt Suzuki was signed in the offseason.

Projects to more offense: More playing time for Mauer (lifetime .323 batting average, .405 on-base percentage) figures to translate to more runs for the Twins.
