The Rays acquired Malloy from the Tigers on Tuesday in exchange for cash considerations.
Malloy had been designated for assignment and is now on the move to a new organization. The right-handed-hitting Malloy has slashed only .209/.311/.346 in parts of two seasons at the major-league level, but he's hit .250/.397/.423 versus left-handed pitching. Malloy will compete for an Opening Day roster spot with the Rays but does have minor-league options remaining.
