Castro MRI results are in

Astros catcher Jason Castro, who left yesterday’s game with what was being called a sprained right knee, has undergone an MRI and the results are in. Astros fans assumed the worst when hearing the news that Castro had injured the same knee that caused him to miss the entire 2011 season — but the news isn’t so bad.
General Manager Jeff Luhnow spoke with media members today and it is being reported that Castro is now considered to be day-to-day.

Apparently, no structural damage was detected. But the Astros are likely to take a cautious approach with their All-Star catcher — especially considering their place in the standings.
Already short-handed at the position, the Astros have added another catcher to the mix. Matt Pagnozzi was acquired today from the Atlanta Braves in exchange for cash considerations. Pagnozzi, the nephew of former big league catcher Tom Pagnozzi, played in 33 major league games between 2009 and 2011. This season he has appeared in 87 games behind the plate for the AAA Gwinnett Braves of the International League.
It’s hard to say how much time Castro will miss. But I hope the organization will be in no hurry to get him back behind the plate. Easing him back in at DH is probably the way to go. Cody Clark has been doing a nice job defensively and the acquisition of Pagnozzi is a step in the right direction.
