Although Mauer is headed for his fifth All-Star appearance and leads the American League in on-base percentage, fans still want more from Mauer, as he has hit just four home runs and driven in 36 on the season.
When Mauer signed his extension, his value was determined as an elite catcher. However, since last year's bout with bilateral leg weakness, he's had trouble staying behind the plate, and that has lead the Twins to try Mauer at different positions.
With the outfield and third base being solidified by Josh Willingham and Trevor Plouffe, the only other option for Mauer is to move him to first base.
While it may not seem like the Twins would get their value by moving him to first, there are several reasons why this is the best scenario for the team.
