2. Seattle Mariners
The Mariners could be the 2017 version of the Cleveland Indians. An addition like Napoli may give the same type of value to a team that was lingering in the middle but had the potential to take a step forward. Felix Hernandez, Taijuan Walker, and James Paxton can be compared to Corey Kluber, Danny Salazar and Carlos Carrasco respectively. The Mariners do not have a Francisco Lindor rookie to breakout, but their lineup could arguably be better.
With Mike Napoli in the heart of the lineup, a run of Robinson Cano, Kyle Seager, and Napoli is a scary trio and one that could make noise in October. In getting a player such as Cano, the Mariners have shown that they are willing to spend money to win now. They have a huge hole at first base currently and if any team is to make a big move for Napoli, it would be the Mariners.
Felix Hernandez is coming off of a down year, especially for his standards, but if they can try to squeeze out a couple of good years this team really could find themselves a legitimate roster. A move in adding a veteran and core piece to the middle of the lineup could really help, and it could make them a legitimate contender in the American League West.
