While much of the roster is still built around aging stars like Roy Halladay, Ryan Howard and Chase Utley, acquisitions such as Ben Revere help project the club's Opening Day age to be more than a year younger than it was last season.
Gone are Shane Victorino (31 in 2012), Placido Polanco (36), Ty Wigginton (34), Jim Thome (41) and Juan Pierre (34). In to replace them are Revere (24 in 2013), Michael Young (36), Darin Ruf (26), Kevin Frandsen (30) and Domonic Brown (25), who's set to begin the season with the big club for the first time in his career.
In 2012, the Phillies' average age to start the season was 30.9 years old. Only the Yankees, at 31.6 years, were older to begin the season, and they were also the only one of the top-five oldest teams to reach the postseason. (The Angels, Dodgers and Rockies rounded out that list.)
But now, even with their large core of older players a full year more mature, the Phillies' expected roster to start the season comes in at a riper 29.6.
Youth on its own, of course, is not necessarily better -- but replacing guys whose bodies are breaking down with players who are up-and-coming and healthy is.
The age gauge in the outfield shifted most dramatically and poses the most questions, especially with a possible double-platoon situation. At least you won't see Ty Wigginton attempting to catch a fly ball in left or Juan Pierre trying to reach second base without two-hopping his throw.
In the case of Young taking over for Polanco, there's a significant difference. Even though the former Texas third baseman is only one year and nine days younger than Polanco, he's played in at least 156 games in each of the past three seasons. Polly hasn't reached the 150-game mark since 2009, when he was a 33-year-old second baseman for the Tigers.
In the Phillies' case, it appears, they're moving in the right direction. And it should stay that way, assuming Jim Thome and Jamie Moyer stay away.
