MLB.com is reporting the Astros are one of a handful of teams interested in catcher Dave Ross.
Ross spent time with the Reds and Red Sox last year, hitting a combined .225 in 60 games and 142 at-bats. He did hit 38 home runs total in '06 and '07 for the Reds, and would be expected to share time at catcher with Humberto Quintero.
