And after taking the pretty aggressive approach of adding Eugenio Suárez, Josh Naylor and Caleb Ferguson, they ended up claiming last year's No. They have an impressive stockpile of desirable prospects, and there is certainly an urgency to win right now, with both Randy Arozarena and J.P. Crawford headed for free agency this winter. At any rate, there has been a lot of talk about Mason Miller possibly heading north to Seattle, which definitely would not come cheap.
