Josh Naylor is stepping right into the Mariners lineup as the new cleanup hitter, and that means Miles Mastrobuoni is heading back to Tacoma. The team’s latest trade brings in some serious power at first base, but it also means saying goodbye (for now) to a versatile player who’s filled in all over the field this season. With so much depth in the infield and outfield, the front office clearly wants more pop in the middle of the order. What do you think—will Naylor’s bat make the difference the M’s need, or will they miss Mastrobuoni’s flexibility? #Sports #Baseball #Mariners
