The Seattle Mariners already pulled off the one big deal they had planned to make leading up to Major League Baseball's trading deadline. The Mariners traded away Cliff Lee for one of the best offensive prospects in the game in Justin Smoak (plus other prospects).
Yet, the Mariners are unlikely finished with their trading deadline work. Seattle is 39-60 and assuredly out of the buyer's market. Yet there are deals within the current roster the Mariners should consider as they look to the future built around Smoak and Felix Hernandez. The Mariners have the pieces, it's a matter of finding the right buyer.
