The Rays currently have four catchers on their 40-man roster, but apparently they're seeking even more depth. Jon Heyman and Scott Miller of CBSSports.com hear from those within the industry that Tampa is believed to be seeking an extra catcher (Twitter links). One executive predicted that Jose Molina won't catch more than 80 games.
Molina, 36, was brought in on a one-year, $1.8MM deal this offseason because of his stellar defense and not his .263/.323/.396 batting line with the Blue Jays over the last two years. The veteran backstop has started 81 games behind the plate just once in his 12-year career (2008), and only twice has he started more than 60 games at catcher. The other 40-man roster catchers - Robinson Chirinos, Jose Lobaton, and Stephen Vogt - have 116 plate appearances at the MLB level combined.
As our Free Agent Tracker shows, there isn't much out there in terms of catching help. It's basically Ivan Rodriguez and Ramon Castro. The Rays have pitching to spare if they want to seek another backstop via trade.
