It won't be surprising if the Seattle Mariners make a blockbuster trade this winter, and not just because the odds of Jerry Dipoto making any kind of trade are never far from 1:1. They have holes to fill, not to mention more blue-chip prospects than they really need.
The Mariners have eight prospects in MLB Pipeline's top 100, a remarkable number that feels even more so considering that they're only a few months out from trading for Josh Naylor and Eugenio Suárez. Those deals cost five players, yet not one of those five was among the club's best prospects.
