Houston, TX (SportsNetwork.com) - The Houston Astros have acquired 19-year-old pitching prospect Akeem Bostick from the Texas Rangers in exchange for catcher Carlos Corporan.

Corporan was designated for assignment on Tuesday after the Astros signed outfielder Colby Rasmus.

Bostick was a second-round pick of the Rangers in 2013. The right-hander finished 5-6 with a 5.17 earned run average in 21 appearances (20 starts) at Single-A Hickory last season.

Corporan batted .235 with six homers and 19 RBI in 55 games with the Astros last season. He has served as Houston's primary backup catcher since 2013. In 198 total games with the Astros, the switch-hitter has compiled 21 doubles, 17 homers and 63 RBI.
