Arizona Diamondbacks offseason outlook: tight budget, pitching needs, and a Burnes opt-out

The Arizona Diamondbacks finished 2026 as the best non-playoff team in baseball, per MLB Trade Rumors' Anthony Franco — and if that sentence reads like a participation trophy, the front office is probably not framing it either. An 86-76 record was not an embarrassing showing, but it was not enough, and the club now enters an offseason reportedly working with a tighter budget while staring at genuine roster needs at the back of the rotation and the bottom of the lineup.

What happened

Anthony Franco's offseason outlook at MLB Trade Rumors lays out the full financial and roster picture for Arizona heading into the winter. The D-Backs fell short of a Wild Card berth for a third consecutive year, finishing with a record that Franco notes was actually better than the Cleveland Guardians — who earned the No. 2 seed in the American League and a first-round bye. The NL's playoff structure, Franco writes, does not entirely absolve the front office of leaving some positions unaddressed that could have made the difference. Still, per the report, ownership remains engaged enough that the club is expected to be active this winter.

The offseason arrives alongside a notable coaching change: per MLB.com's Steve Gilbert, pitching coach Brian Kaplan will not return for the 2027 season after two years in the role. That departure adds another layer to an already complicated pitching staff situation, and whoever fills the role will inherit a rotation with real questions at the back end.

Why it matters

The financial architecture here shapes almost every move Arizona can make. Per Franco's reporting, the club carries $460MM in total future commitments and $127MM in 2027 guarantees alone — $14MM of that deferred. That is a significant load for a club that Franco describes as probably working with a tighter budget this winter.

The core of the roster is locked in and expensive. Corbin Burnes sits at $140MM through 2030, with $44MM in deferrals. Ketel Marte runs $87.5MM through 2031, with an opt-out available after the 2030 season and $35MM deferred. Corbin Carroll is at $87MM through 2030, with a 2031 club option attached. Brandon Pfaadt is under contract at $40MM through 2030, including the buyout of a 2031 club option. Geraldo Perdomo is at $35MM through 2029. Eduardo Rodriguez carries $25MM through 2027, including a $6MM buyout on a vesting or mutual option for 2028. Merrill Kelly is at $21MM through 2027. Nolan Arenado is at $15MM through 2027, with the Cardinals paying $9MM at the end of that season as a condition of the trade that brought him to Arizona. Justin Martinez rounds out the guaranteed group at $12.5MM through 2029, with club options for 2030 and 2031.

The club also owes a $5MM buyout to released outfielder Lourdes Gurriel Jr., per the report.

One significant variable sits at the top of that list: Burnes holds an opt-out on the remaining four years and $140MM of his deal. Whether he exercises it will be one of the more consequential decisions of Arizona's winter, and it is entirely his to make.

Where the club stands

Arizona finished 86-76 (.531), third in the NL West, 14 games back of the division leader. The club ranked fourth in Wild Card positioning, finishing 2.0 games relative to the cut line — close enough to feel the door, not close enough to walk through it. The Diamondbacks closed the year on a two-game losing streak, eliminated from both the division race and the Wild Card. The gap between where they finished and where they needed to be is the number the front office will be living with all winter.

It is worth pausing on that 86-76 mark for a moment. Per Franco, it was better than the Guardians' record — a team that earned a first-round bye in the AL playoffs. The NL's competitive depth is a real structural factor, not an excuse, and Franco acknowledges both things simultaneously: the league is hard, and there were addressable gaps.

What we don't know yet

Franco's report identifies several players entering free agency whose futures with the club are unresolved: Michael Soroka, Zac Gallen, Jonathan Loáisiga, Kevin Ginkel, Taylor Clarke, Ryan Thompson, James McCann, Ildemaro Vargas, Dennis Santana, and A.J. Puk. Gallen, in particular, represents a meaningful rotation question given the staff's depth concerns.

On the arbitration side, the club projects to owe Lars Nootbaar $6.3MM, Gabriel Moreno $6.1MM, Ryne Nelson $3.4MM, and Pavin Smith $2.5MM, per MLBTR contributor Matt Swartz's projections. Franco flags Smith as a non-tender candidate.

Soroka also holds a $10MM mutual option with a $1MM buyout, per the report — a decision that falls to both sides.

The Burnes opt-out is the headline unknown. It is a player option on four years and $140MM, and the answer to it restructures Arizona's entire offseason calculus. If Burnes walks, the club loses its top starter and gains back budget flexibility; if he stays, the rotation's foundation holds but the financial constraints tighten further. Either outcome lands with real force on a club that is already threading a needle between competitiveness and payroll discipline.

What to watch

The pitching staff is the most pressing area, and not only because of the free agents. The departure of Brian Kaplan means Arizona will be hiring a new pitching coach to work with a rotation that has genuine questions behind Burnes and Pfaadt. Who fills that role — and what philosophy they bring — matters for a group navigating real depth concerns heading into 2027.

A week removed from the end of the regular season, the Rodriguez situation is worth keeping in mind. Per earlier Posterior Wire reporting, Eduardo Rodriguez posted a 2.89 ERA in 2026 despite ERA estimators projecting something closer to 4.4, driven by elite pitch location — a 109 Location+ — rather than raw stuff. That kind of performance is genuinely valuable and genuinely difficult to project forward, which is exactly the kind of uncertainty a front office navigating a tight budget does not love. His $25MM through 2027 is already on the books; the question is whether the results hold without the coaching continuity that surrounded them.

Two days after the Kaplan news broke, Derek Law elected free agency after being outrighted to Triple-A by Arizona following a DFA in mid-September, per earlier Posterior Wire reporting — a small but illustrative note about the kind of roster churn the club is already managing at the margins of the 40-man.

The lineup depth question, which Franco identifies alongside the pitching concerns, will require either a free-agent addition or meaningful internal development. With $460MM in future commitments already on the books, the margin for large new guarantees is not wide. How aggressively Arizona moves in the market, and on which positions, will say a great deal about how ownership's continued engagement translates into actual dollars this winter.

The Diamondbacks were 2.0 games from the postseason. That is close enough to build on. Whether the budget allows them to close that gap is the question the next several months will answer.
