Cubs president of baseball operations Theo Epstein emphasized on Thursday that Alfonso Soriano remains a valuable offensive asset, but Epstein also left the door open to the type of move that led to Carlos Zambrano being shipped to the Marlins earlier in the day. Hours after the Cubs announced the Zambrano move, Epstein said he would pursue another trade if it made sense moving forward. Part of that equation could be how much of Soriano's contract the Cubs would be willing to pay. Soriano, who turns 36 on Saturday, is owed $54M over the next three seasons. And like Zambrano, Soriano has a full no-trade clause.
