Following the conclusion of the 2026 season, key members of the Arizona Diamondbacks roster are set to enter free agency. The team must navigate these player departures alongside the impending expiration of the collective bargaining agreement on December 1, 2026.
Why it matters
These players reached the end of their current contracts, marking a critical transition period for the organization as it manages its roster. The potential for a lockout following the collective bargaining agreement's expiration adds a layer of uncertainty to the offseason.
In 2026, Kevin Ginkel appeared in 74 games, while Michael Soroka pitched 116 innings with a 3.40 ERA and Jonathan Loaisiga recorded 67 innings with a 2.42 ERA. A.J. Puk enters this period having not made a major league appearance since April 17, 2025.
The players
Zac Gallen
He is a veteran starting pitcher who signed a contract worth $22.03 million in the 2025 offseason.
Kevin Ginkel
A relief pitcher who proved to be a durable part of the bullpen by appearing in 74 games during the 2026 season.
Michael Soroka
A pitcher who recorded a 3.40 ERA over 116 innings in 2026 and holds mutual interest in remaining with the Diamondbacks.
Jonathan Loaisiga
He is a pitcher who maintained a 2.42 ERA across 67 innings of work during the 2026 campaign.
A.J. Puk
A pitcher who has been sidelined from major league competition since April 2025.
The details
Players such as Zac Gallen, Kevin Ginkel, Michael Soroka, and Jonathan Loaisiga are among those entering free agency. While the team has indicated interest in a reunion with Michael Soroka, others like Ryan Thompson, who last played on August 4, 2026, face uncertain futures.
Timeline
April 17, 2025: Last major league appearance for A.J. Puk.
August 4, 2026: Last game appearance for Ryan Thompson.
November 9, 2026: General manager meetings begin.
December 1, 2026: Expiration of the collective bargaining agreement.
Season Trajectory
This roster turnover follows the expiration of the collective bargaining agreement, which sets the rules for how teams manage player options and qualifying offers. The outcome will shape the team's competitive balance as they head into the next league year.
The departure of core arms like Kevin Ginkel and Jonathan Loaisiga necessitates immediate bullpen reinforcements before spring training begins. Fantasy managers should monitor these free agency movements to track the shifting roles of pitchers in the Diamondbacks rotation and bullpen.
The takeaway
Free agency periods are essential windows for teams to recalibrate their roster depth through strategic acquisitions. Readers tracking the team should watch for early offseason signing announcements to see how the front office addresses these departures.
