Mariners Nail Naylor

 Sources say Josh Naylor is set to sign a five year contract with the Seattle Mariners.  

Naylor, a trade deadline acquisition from the Arizona Diamondbacks, was a spark plug, both during the race to get into the playoffs and also in the playoffs, where the Mariners came close to playing in its first World Series. 

The first baseman has said that he loves hitting in T-Mobile, the Mariners home ballpark, long considered a pitcher's park.
