The Minnesota Twins have signed Alexi Casilla to a one-year deal for almost $1.4 million, according to Twins Communications Director Mike Herman (via Rhett Bollinger). The deal allows each side to avoid arbitration.

Casilla, 27, is a switch-hitting middle infielder with five seasons under his belt (six if you count the nine games in which he appeared in 2006), all with the Twins. He's not much of a hitter, swinging a .252 / .310 / .337 career line.

That .310 OBP is what should pop out to you as something of a oh my god, if he never swung at all his OBP might be higher. Then again, he doesn't really need to be that good of a hitter for that low of a cost. Note that he's more or less accounted for himself in the big leagues -- producing around zero Wins Above Replacement for his career (with nearly one and a half last season). Read: he's what we talk about when we say 'replacement player,' but a hair better.
