The first major signing of the offseason is in the books as first baseman Josh Naylor and the Seattle Mariners agreed to a 5-year deal. The details of the deal are still being worked out, but this looks to be a perfect fit both for Naylor and the Mariners.

The Seattle Mariners have reached an agreement with top free agent target, first baseman Josh Naylor, on a five-year deal, a source confirmed to FOX 13 Seattle on Sunday night.

The Seattle Mariners bolstered their bullpen thanks to the addition of a Los Angeles Dodgers pitcher who was viewed as expendable.
