Kennedy was recalled from the Phillies' spring training complex Sunday.
He is not in Sunday's lineup against the Nationals, but Kennedy will serve as a capable righty bench bat with Austin Hays (back) banged up. Kennedy, who turns 26 next week, has played sparingly in the majors and slashed .294/.400/.500 with 10 home runs in 300 plate appearances for Triple-A Lehigh Valley.
