Orioles have expressed interest in Wandy Rodriguez (Tolleson recalled)

You can add left-hander Wandy Rodriguez to the list of pitchers who are on the Orioles' radar. The Orioles have contacted the Astros about Rodriguez, according to an industry source. No word on the level of interest or which players have been discussed, but executive vice president Dan Duquette is considering Rodriguez as a possibility for his ever-changing rotation. Rodriguez is owed about $5 million for the rest of 2012 and is signed through next season, when he'll make $13 million. The Astros also hold an option for $13 million in 2014, with a $2.5 million buyout, but it becomes a player option if Rodriguez is traded. Also, the option becomes guaranteed if Rodriguez meets certain performance clauses. Got all that? Rodriguez, 33, is 6-6 with a 3.54 ERA in 17 starts this season. He's 79-81 with a 4.03 ERA in eight major league seasons, all of them spent with the Astros, and has won more than 11 games in a season only once in his career, going 14-12 with a 3.02 ERA 2009. Rodriguez is starting tonight against Milwaukee's Zack Greinke, who's also drawing interest from the Orioles. It's a safe assumption that the club will have a scout at Minute Maid Park. The Astros are in sellers mode, as evidenced by the deal earlier this week that sent first baseman Carlos Lee to the Marlins. Note: The Orioles made their roster move official, recalling infielder/outfielder Steve Tolleson from Triple-A Norfolk to replace pitcher Jake Arrieta on the 25-man roster. This is Tolleson's third stint with the Orioles in 2012. He's batting .220 (11-for-50) with two home runs and six RBIs in 17 games. Tolleson has batted .291/.382/.379 with one home run and 13 RBIs in 32 games with the Tides this season.
