Is Justin Martinez the Diamondbacks' Next Closer or a Trade Chip? 

The Arizona Diamondbacks have made a bold move by signing reliever Justin Martinez to a five-year, $18 million deal, but the question remains: is this a smart investment for a reliever? Martinez had a solid 2024 season with eight saves and a 2.48 ERA, but his 36 walks in 72 2/3 innings raise eyebrows.

As fans and fantasy players, we often debate the value of relievers in long-term contracts. Is it wise to commit to a reliever for five years, especially one with a history of control issues? Could this be a case of the D-backs banking on Martinez's potential to rein in his walks and become a dominant closer? Or are they setting themselves up for disappointment?

Moreover, with manager Torey Lovullo still weighing his options for the closer role between Martinez, A.J. Puk, and Kevin Ginkel, how do you see this situation unfolding? Will Martinez emerge as the go-to guy, or will the D-backs find themselves in a closer-by-committee situation?

Let’s also consider the trade implications. If Martinez can get his walks under control, could he become a valuable asset for the D-backs to flip for a significant return?
