Ruben Amaro is confident that the Philadelphia Phillies will receive strong production from their aging core next season.

The Phillies lost 89 games in 2013 and have millions of dollars committed to Ryan Howard, Chase Utley, Jimmy Rollins, Cliff Lee, Jonathan Papelbon, Carlos Ruiz and Cole Hamels.

"We've committed to them," Amaro said. "We have to roll with them. I believe in these players. I know Ryne Sandberg does. I know our staff does. The proof will be in the pudding. If they don't play well, then we won't do well."
