The Rays have designated infielder Ryan Roberts for assignment, according to Marc Topkin of the Tampa Bay Times (on Twitter). The move will clear a 40-man roster spot for Alex Cobb to be reinstated from the 60-day disabled list.
Roberts, who turns 33 next month, hit .247/.295/.377 with five homers in 173 plate appearances for the Rays this season. He was used primarily at second base for the Rays this season, but he does carry more than 1700 innings of Major League experience at the hot corner as well. Roberts hit .305/.345/.500 against left-handed pitching but floundered against right-handers, hitting just .188/.244/.50. He's typically handled lefties much better throughout his big league career, which spans parts of eight big league seasons with the Blue Jays, Rangers, D-Backs and Rays.
