Arizona Diamondbacks Prioritizing Starting Pitching via Trade

Following a season that exposed heavy strikeout deficiencies on the mound, the Arizona Diamondbacks are actively prioritizing controllable starting pitching through the trade market this winter. General manager Mike Hazen confirmed to Nick Piecoro of The Arizona Republic that financial constraints and planned payroll reductions make free agency an unlikely route for rotation upgrades, steering the franchise toward the trade block.

Fantasy & Market Impact

• Rotation Dynamics: Eduardo Rodriguez, Brandon Pfaadt, and Corbin Burnes anchor the 2027 projected staff, but acquiring a high-strikeout arm remains essential to hedge against regression.
• Trade Capital: Right-handed hitting depth pieces like Jordan Lawlar and Ryan Waldschmidt stand as the primary currency for front-office negotiations.
• Market Value: Premium controllable starters such as Bryce Miller or Will Warren will command significant prospect capital, impacting Arizona’s rebuilding flexibility.

Rotation Numbers and the Strikeout Deficit

The Diamondbacks posted a middling 4.28 ERA from their starting staff this year, but the underlying peripherals tell a more vulnerable story. Arizona starters generated a meager 9.6% strikeout-minus-walk rate, beating out only the Colorado Rockies across the league. While the staff excelled at limiting walks, the severe lack of swing-and-miss stuff left the defense exposed in high-leverage frames.

Eduardo Rodriguez anchored the rotation stability by logging a 2.89 ERA across 32 starts, pacing the staff with 3.2 fWAR despite middling peripherals. Michael Soroka and Brandon Pfaadt followed closely with earned run averages under 3.40. Soroka leaned on an above-average 24.1% strikeout rate, while Pfaadt deployed heavy ground-ball tendencies and precise command to navigate opposing lineups.

Pitcher	Starts	ERA	fWAR / Key Metric
Eduardo Rodriguez	32	2.89	3.2 fWAR
Michael Soroka	—	<3.40	24.1% K-rate
Zac Gallen	20	6.07	1.62 HR/9

Roster Decisions and Payroll Realities

Financial considerations shape every move on Hazen’s ledger heading into the offseason. Soroka faces unrestricted free agency once he declines his end of a $10 million mutual option. Although both the organization and the pitcher have expressed mutual interest in a reunion, the ultimate price tag remains undetermined. Arizona must simultaneously allocate resources toward the bullpen, first base, and left-handed hitting depth, complicating any aggressive spending.

Meanwhile, Zac Gallen reaches free agency after a turbulent age-30 campaign. Gallen stumbled to a career-worst 6.07 ERA across 105 1/3 innings, surrendering 19 home runs and managing just a 13.6% strikeout rate. That performance dipped below replacement level according to FanGraphs metrics, all but ensuring the front office will look past a reunion. Corbin Burnes locks in his spot for the upcoming campaign, leaving a projected 2027 rotation featuring Rodriguez, Pfaadt, Burnes, Merrill Kelly, and Ryne Nelson.

Trade Chips and Potential Target Profiles

To secure a controllable arm without increasing payroll via free agency, Arizona must tap into its positional depth. Jordan Lawlar and Ryan Waldschmidt emerge as logical trade candidates. Lawlar spent the majority of the season battling wrist and hamstring injuries on the injured list, though his pedigree as a top prospect remains intact. Waldschmidt posted a 93 wRC+ across 284 plate appearances. Packaging either player with mid-tier prospects represents the most viable avenue to acquire external rotation help.

Several Major League clubs hold surplus starting pitching. The Seattle Mariners feature Bryan Woo and Bryce Miller, with Miller standing out as a realistic target following a tough second half. Miller registered a 6.14 ERA over his final 13 starts beginning July 9th, experiencing dips in both strikeout and walk rates. Alternatively, the Los Angeles Angels could shop Reid Detmers once again, while the New York Yankees possess depth pieces like Will Warren, who posted an above-average 23.3% strikeout rate and remains controlled through 2030. Pittsburgh Pirates right-hander Carmen Mlodzinski presents another overqualified depth option as trade discussions heat up across the league.
