Fans are understandably frustrated with the offense the Rays have received from the catcher position throughout the history of the franchise. Free agent catcher Jason Castro is one of the better options available on the market, and a sensible choice for the Rays, should they want to finally sign an established backstop.
Why does Jason Castro fit?
You can begin the argument for Castro around offense.
The Rays already have a good hitting option against left handed pitching in Curt Casali. Casali hit .230/.305/.432 and 101 wRC+ in 82 PA against southpaws. In his career he’s put up a 106 wRC+ against left handed pitchers and put up a solid season defensively in 2016 with +3.
