The Rays have announced they have designated catchers Robinson Chirinos and Stephen Vogt for assignment. The Rays now have ten days to trade, release, or outright Chirinos and Vogt to the minors.

The moves were needed to open space on their 40-man roster for first baseman/DH Shelley Duncan and relievers Jamey Wright and Juan Carlos Oviedo. Oviedo was then transferred to the 60-day disabled list, as he continues his recovery from Tommy John surgery.

Duncan's promotion was necessitated by a right calf strain suffered by Luke Scott, who was placed on the 15-day disabled list. Executive VP of Baseball Operations Andrew Friedman told reporters, including Marc Topkin of the Tampa Bay Times (via Twitter), Duncan won the job due to his extra base-hit ability and because he adds value with his power.

Chirinos was acquired in the Matt Garza trade and appeared in 20 games for the Rays in 2011 producing a slash line of .218/.283/.309 in 60 plate appearances. He sat out the 2012 season due to a concussion.

Vogt, a 12th-round selection by the Rays in the 2007 draft, made his MLB debut last season, but went hitless in 25 at-bats. He has fared much better at the plate during his six-year minor league career (.290/.360/.448), including numbers of .272/.350/.424 in 396 plate appearances in 94 games at Triple-A Durham in 2012.
