Napoli has been long rumored as a potential target for the Red Sox brass, and it didn't take long for them to bring Napoli into the fold.
It's also speculated that Napoli will make the positional move from catcher to first base, which makes sense on a lot of levels. Boston is in dire need of a first baseman after trading Adrian Gonzalez and letting James Loney walk. Also, Napoli has never been known for his defensive abilities behind the plate.
On top of all that, he's 31 years old and could certainly use less wear-and-tear on his knees. Last year with the Texas Rangers, Napoli hit 24 home runs and drove in 56 runs while hitting .227.
Napoli has always been a terrific hitter at Fenway Park, with a lifetime .306 batting average in the historic stadium.
