"According to ESPN.com, Joe Borowski flunked a physical that would have given him a multiyear deal with the Phillies.
Apparently, there was enough wear and tear on his shoulder that the Phillies didn't want to commit long-term. Borowski's agents, Ron Shapiro and Michael Maas, continue to field one-year offers from several clubs, and it seems that the Phillies still could consider him on a shorter deal."
