Pirates Acquire Wandy Rodriguez

The Pirates have acquired left-handed starter Wandy Rodriguez from the Astros in exchange for minor leaguers Rudy Owens, Robbie Grossman, and Colton Cain

The Astros will also pay some of the remaining salary owed to Rodriguez at least through 2013 and perhaps through 2014, as the club option for that year became a player option when Rodriguez was traded, per a stipulation in his contract. The Astros' yearly contributions to Rodriguez's salaries break down as such: $1.7MM in 2012, $8.5MM in 2013, and potentially $7.5MM in 2014.

Rodriguez, 33, has posted a 4.04 ERA, 7.5 K/9 and 2.2 BB/9 in a little over 1,300 career innings, all with the Astros. The Wasserman Media Group client signed a three-year, $34MM extension with Houston prior to the 2011 season.

Grossman, an outfielder, is the best of the three prospects acquired by Houston, according to Jim Bowden of SiriusXM ESPN radio (Twitter). A 22-year-old switch-hitter, Grossman was a sixth-round draft choice of the Bucs in 2008. He's hit .262/.374/.403 with seven homers in 413 plate appearances this season with Double-A Altoona.

Owens, 24, had a 3.14 ERA in 19 starts with Triple-A Indianapolis this season. He has been added to Houston's 40-man roster.

Tom Singer of MLB.com first broke that the trade was close. Jon Heyman of CBSSports.com confirmed that it was official and added in financial details (via Twitter), as did Rob Biertempfel of the Pittsburgh Tribune-Review (Twitter). And club press releases added which players the Astros received.
