"The Tigers' surprising signing of Prince Fielder has certainly sent shockwaves throughout baseball. It obviously makes Detroit that much more formidable in the AL Central, and there are myriad fantasy implications not just for Fielder, but for many members on the Tigers roster.
As far as Prince goes, he'll certainly miss Miller Park. The rotund first baseman has an OPS of .965 there during his career (.896 on the road), and Miller Park is surpassed only by Coors Field among National League stadiums in terms of being hitter-friendly over the last three seasons (according to Baseball-Reference's three-year park factors for batters). Twenty-four of his 38 bombs this past season were hit at home.
Comerica Park has been rather hitter-friendly in recent seasons, but that's mostly been the result of moving the left-field fence in. Just eleven of Prince's homers went to left field in 2011, so he won't see a whole lot of the benefits from the shorter left field porch. Fielder will also have to figure out a new group of pitchers, which can sometimes require an adjustment period.
The bottom line is that Fielder is going to be an elite power hitter no matter where he's playing. It might be wise to knock down expectations for him just a hair, though."
