The Astros announced that they’ve designated catcher Carlos Corporan for assignment in order to clear a 40-man roster spot for Colby Rasmus.

The 31-year-old Corporan hit .235/.302/.376 with six homers in 190 plate appearances for Houston last year. Over the past three seasons, he’s proven himself to be a competent defender (in terms of pitch-framing and throwing out base stealers) while exhibiting low batting average and OBP marks with respectable pop for a catcher.

Of late, Corporan has drawn trade interest from the Rangers, so it certainly seems possible that Houston will be able to move him before he must be exposed to outright waivers. Given Texas’ interest, I’d imagine that, at the very least, a deal for cash considerations could be reached, if not a trade to send a minor leaguer to Houston in exchange for Corporan’s services (be it from the Rangers or another club).

Corporan was arbitration-eligible for the first time this offseason and agreed to a one-year, $975K deal with Houston just last Thursday. That might take away a bit of his trade value, although that sum is largely negligible for a big league club that would have interest in trading for him.
