The Phillies are known to hire former Phillies to serve in key roles.  Among the coaching staff, Pete Mackanin, Larry Bowa, Mickey Morandini, Juan Samuel, and Matt Stairs are all former Phillies players.  Each Spring, several former Phillies serve as guest instructors.  This year featured Brad Lidge, Wes Helms, Chad Durbin, Mike Schmidt, Charlie Manuel and Larry Andersen.  So, it makes sense that Roy Halladay would play a role with the club going forward.

Todd Zolecki of MLB.com reports that Halladay could fill a yet-to-be-specified role in the Phillies organization:

The Phillies and Halladay have been talking recently about finding a role for him in the organization, a person with knowledge of Halladay's visit said Tuesday. It is unclear what responsibilities Halladay might have with the team, but it seems likely he will be roaming Spectrum Field and Carpenter Complex in a Phillies uniform before the end of Spring Training.

Filling such a role would be easy for Halladay.

Dating back to his time with the Toronto Blue Jays, who train in Dunedin, Florida, Halladay has lived in the area.  The commute to Spectrum Field and the Carpenter Complex would be easy for Halladay.  Even after the Phillies head north for the season, extended Spring Training, the Gulf Coast League, and Class-A Clearwater all are housed at the facility.
