Doumit is known more for his offense rather then his defense. The Twins didn't sign him for his defense but going to the AL which has the DH should help give him a little boost in the offensive category. The Twins will take all of the offensive help they can get. Besides Joe Mauer the Twins got awful production from their catchers last year.
Doumit out produced Drew Butera and Rene Rivera in K%, BB/K, OBP, SLG, OPS, ISO, BABIP, wRAA, wOBA and wRC+. If you look at this table you'll be able to see that Doumit destroyed those categories. Rivera and Butera were really pathetic.
|Ryan Doumit||Pirates||236||6.8 %||14.8 %||0.46||.303||.353||.477||.830||.174||.331||8.3||.360||129|
|Drew Butera||Twins||254||4.3 %||16.5 %||0.26||.167||.210||.239||.449||.073||.194||-23.0||.202||20|
|Rene Rivera||Twins||114||7.0 %||28.1 %||0.25||.144||.211||.202||.412||.058||.194||-11.2||.192||13|
For his career Doumit has been a solid player when healthy. He has decent power, posting a .174 ISO. He does a good job at getting on base, his career OBP is .334. His 104 wRC+ is slightly above league average but Doumit is a slightly above league average player. Like I stated earlier he isn't a good defensive player but makes up for it offensively. Doumit should be able to put up at least 2 WAR this season giving the Twins $10 million dollars of value. If Doumit can come into Minnesota and do what he's good at which is getting on base, hitting for some power and being a versatile player then Minnesota got a good deal.
So far I've liked what the Twins have done this off-season. They got a quality shortstop in Jamey Carroll and a solid versatile offensive player in Ryan Doumit. With about $20 million dollars left to spend they should be able to at least get an outfielder and a decent pitcher.
