How does Jon Rauch fit in the Twins' bullpen?

Before the virtual ink dried in my Ron Mahay post, I was informed that the Twins have acquired Jon Rauch from the Arizona Diamondbacks.

How does he fit?

Here is the data:



Rauch is slightly below the AL average reliever but better than Mahay. Thus the addition of Mahay and Rauch and the subtraction of the likes of Bobby Keppel and Philip Humber will help the Twins. Rauch is under contract for 2010 for about $3 million



Here are Joe Rauch's career numbers against AL Batters: they collectively hit .169/.228/.265; and he has 1.14 ERA, 0.864 WHIP 9.4 K/9, 3.73 K/BB (in 39.1 IP) these are excellent numbers and he could prove to be a valuable acquisition not only for 2009 but for 2010 as well
