The Philadelphia Phillies have shuffled their roster a bit this offseason, but they have more work to do.

They traded Jimmy Rollins, Marlon Byrd and Antonio Bastardo and watched A.J. Burnett and Kyle Kendrick leave.

However, the Phillies still have numerous veterans on the roster including Cole Hamels, Ryan Howard, Chase Utley, Jonathan Papelbon and Cliff Lee.

"We didn't necessarily expect to make a full transition in a two- or three-month period of time," Ruben Amaro said. "The process doesn't start on Oct. 1 and it doesn't end on Feb. 15. It continues. We'll continue to look at ways to get younger and more athletic. There's still a lot of work to be done.

"I think we've made some pretty decent progress as far as bringing some players and some talent into our system, particularly at the upper levels, that we hope will provide the depth that is necessary to move us forward. It's not a three-month process. The process is going to take a little longer and we understand that we have those challenges. We'll continue to work on that transition."
