Infante agreed to a minor league contract with the Phillies on Monday, Todd Zolecki of MLB.com reports.
Infante spent the majority of the season at the Triple-A level, where he posted a 2.77 ERA with 41 strikeouts in 48.2 innings. He hasn't appeared in the majors since 2010, but the 28-year-old could work his way into the big league bullpen if he can continue finding success in the minors.
