Wandy Rodriguez (back) threw live batting practice Monday afternoon in Astros camp. Rodriguez was unable to finish a bullpen session last week due to tightness in his back, but he's already over the minor ailment and should have no restrictions going forward. The 33-year-old southpaw posted a 3.49 ERA and 166/69 K/BB ratio in 191 innings last season and seems likely to serve as Houston's Opening Day starter.
