The Giants have signed Jeremy Affeldt to a two-year deal worth $8M. The left-hander isn't really a matchup guy, and that's a good thing; he's been a versatile and durable reliever, making 74 and 75 appearances, respectively, since moving to the bullpen on a full-time basis in 2007. Last season with the Reds he was used as a multi-inning setup man, and he averaged more than a strikeout an inning. With the Rockies in 2007, he threw only 59.0 innings, which was really a misuse of his strengths. Almost every bullpen could use a guy like him, and the price looks reasonable.
