Wandy Rodriguez ended his bullpen session early Thursday due to some tightness in his back. Rodriguez expects to throw another bullpen session in the next two days, so it doesn't sound like a major concern. The 33-year-old left-hander compiled a 3.49 ERA and 166/69 K/BB ratio across 191 frames last season. We'd like him better in fantasy leagues if he was traded to a contender, but he should still be useful in 2012.
