The Phillies selected Ellis' contract from Triple-A Lehigh Valley on Thursday, Scott Lauber of The Philadelphia Inquirer reports.
Ellis had a 1.009 OPS with eight home runs in 21 games this season between Lehigh Valley and Double-A Reading. The 27-year-old can play all over the infield but will primarily serve as the Phillies' first baseman versus left-handed pitching while Alec Bohm (hamstring) is on the shelf.
