11:08am: The deal is official, per Rangers executive VP of communications John Blake (via Twitter). To create roster space, the club designated righty Gonzalez Germen, who was acquired only yesterday.

9:40am: The Rangers have agreed to a deal to acquire backstop Carlos Corporan from the Astros, Evan Drellich of the Houston Chronicle reports on Twitter. Corporan was designated for assignment yesterday to create roster space for the signing of Colby Rasmus. Righty Akeem Bostick is headed to the Astros in return, Jeff Wilson of the Forth Worth Star-Telegram tweets.

Corporan, 31, is set to earn $975K in his first season of arbitration eligibility. That means that he’ll come with two more years of control. His role was occupied by trade acquisition Hank Conger, and the presence of the younger Max Stassi rendered Corporan a largely redundant piece for Houston.

The switch-hitter should, however, be more useful for a Rangers club whose big league options included Robinson Chirinos, who had never even seen 100 plate appearances in a big league season before last year, along with largely untested 23-year-old Tomas Telis and minor league non-roster invite Chris Gimenez.

Last year, Corporan put up a .235/.302/.376 slash and six home runs over 190 trips to the plate. That line is fairly representative of Corporan’s offensive profile in the majors: low-average, low-OBP, solid power. In a backup role in Houston, he has rated out as a reasonably capable option behind the dish.

Bostick, 19, was a (below-slot) second round pick out of high school in 2013. He seems a nice return for a player who was in DFA limbo, though Corporan’s market was surely active before he technically lost his roster spot. Bostick struggled to a 5.18 ERA in 92 Class A frames last year, though that may have been a somewhat aggressive assignment. Kiley McDaniel of Fangraphs included him at the tail end (27th) of his recent list of the most promising Rangers prospects, explaining that Bostick has plenty of raw talent but is in need of refinement.
