Diamondbacks' contract spending this offseason has been roughly in line with what the market dictates — no major steals, but no egregious overpays either. Across 4 contracts, 4 grade out as good value and 0 look like overpays based on comparable deals around the league. The best bang-for-the-buck deal was Kevin Ginkel (A) at $2.7M/yr — getting rhp production well above the price point. The priciest commitment relative to production was Carlos Santana (B) at $2.0M/yr — the first baseman market may have been richer than the on-field return suggests. The spending approach is neither aggressive nor conservative — a wait-and-see approach from a financial perspective.

Mike Hazen has put together a solid set of 2026 moves for the Diamondbacks, with more well-received decisions than misses. Of 42 graded moves, 16 landed well with the fanbase, 20 drew mixed reactions, and 6 were viewed negatively. The standout move was bringing in Adrian Del Castillo on (A+), which generated the most positive buzz. The most questioned decision was the Jack Martinez trade (F), which drew the sharpest criticism. The overall direction has been well-received — this front office is building with a clear vision.

About this general manager
Mike Hazen is the general manager of the Diamondbacks, in his 10th year as the lead executive. FanVerdicts evaluates MLB GMs on the same four-grade framework applied to players and teams: Contract Value Index for the GM's contract portfolio (the deals they signed), Performance for the on-field results of the players they assembled, Sentiment for media and fan perception of recent moves, and Fan Verdict for community voting on the GM's body of work. Current grades for Mike Hazen: Contract Value Index C+, Performance C+, Sentiment B-, Fan Verdict pending.
Each GM grade is rolled up from the underlying transactions attributed to that GM's tenure. When a GM signs a player, that signing's Contract Value Index grade flows into the GM's portfolio score; the same player's subsequent performance and sentiment grades flow into the GM's respective summaries. Phased attribution applies for new GMs: the first three years weight the prior GM's legacy deals at 100%/66%/33%, ramping the new GM's ownership of roster outcomes.
For broader context, the MLB hub has team rankings, GM report cards, and the transactions feed. The MLB GM rankings page ranks every front office side-by-side on the same four dimensions.
