It’s no secret that the Phillies could have a different look a year from now. Chase Utley, Carlos Ruiz and Roy Halladay are all entering the final season of their contracts. Maybe they will be back in 2014, maybe they won’t. Though signed through 2015, Cliff Lee is no sure thing to return next year. It’s not difficult to imagine him being trade bait if the team is out of contention in July. Change will mean opportunity for young players. Phillies officials will get the chance to look at several of these young players in big-league camp this spring. Some of these players have already gotten looks in the major leagues. They include Freddy Galvis, who could be a candidate to play second base if Utley doesn’t return next season; Darin Ruf, a candidate for an outfield spot this spring; and a host of relief pitchers that includes Phillippe Aumont, Justin De Fratus, Michael Schwimer, Jake Diekman and B.J. Rosenberg. A number of players yet to appear in the majors will be in this camp, either by recent inclusion on the 40-man roster or by invite. Most of these players will be sent to minor-league camp in early March so they can get ready for their seasons, but they could stick around a lot longer in the future. Let’s take a look at some of these intriguing youngsters.
