Bullpen again an offseason renovation project for D-Backs

Diamondbacks have struggled with their bullpen in recent seasons. They have signed Archie Bradley, Andrew Chafin and Ken Giles over the past five years. The relief market is a tricky place to spend. The team might be positioning themselves to construct a better bullpen this winter. It's possible they will sign pitchers like Fernando Rodney, Greg Holland, Joakim Soria and Mark Melancon. A few years ago, the Mariners moved Edwin Diaz in exchange for the sixth overall pick in the previous draft, Jarred Kelenic and the opportunity to shed roughly $100 million of Robinson Cano’s contract.
