Gabe KaplerSam Fuld I speculated on Twitter yesterday

Fuld and Warthan were both members of the 2017 Team Israel in the World Baseball Classic that went on a very suprising and competitive run  Fuld was the center fielder and leadoff hitter for Team Israel, despite having been out of major league baseball since 2015.   Werthan was tasked with preparing Team Israel for their opponent during each round in the tournament.

Werthan comes to the Phillies from the Baltimore Orioles organization.  For Baltimore, they are losing their advanced scouting coordinator.  Some reports such as Camden Depot say that Werthan's talents were not being utilized well by manager Buck Showalter.  That should be to the Phillies' advantage.

Fuld technically was not retired, though he had not played in professional baseball since he batted .197 for the Oakland Athletics in 2015.  Fuld had shoulder surgery prior to the 2016 season and got some interest from major league teams prior to 2017.  However, Fuld will now officially retire and join the Phillies.
