Namely reliever Luis Ayala, to a 1-year, $1.3 million contract.
Having just done a post analyzing Matt Guerrier's horrible 2008, I'm struck by how similar Ayala's stats are. Like Guerrier, Ayala doesn't have big strikeout credentials (5.83 K/9 for his career), yet neither of them had had a bad season until last year. Ayala's K/BB rate is just about 3/1, so he fits in with the Twins' pitching model. But, as with Guerrier, he was hurt last year by an unusually high BABIP and BB/9. And, as with Guerrier, it's reasonable to expect those numbers to swing back toward his solid career averages.
Not a bad pickup, although I'm not sure how useful it will prove to be having 2 Guerriers in the bullpen. Sadly, this would appear to dash my hopes that the Twins would re-sign Dennys Reyes, thereby freeing up Craig Breslow and Jose Mijares to be setup men and not just LOOGYs. Oh, well. At least we can't say the Twins didn't sign any free agents this offseason.
