Diamondbacks part ways with Jacob Amaya after Triple-A stint, transactions roundup also notes Conley, Arroyo, Hartwig

In a minor-league roster update that will not move major-league standings, the Arizona Diamondbacks released infielder Jacob Amaya from his minor league contract, according to MLB transactions coverage published Tuesday. Amaya’s 2026 performance with Triple-A Reno included a slash line of.253/.361/.420 across 293 plate appearances, a production profile that suggested a disciplined hitter with some power and on-base ability at the Triple-A level.

The release comes with an important caveat about the timing of his season. MLB transactions coverage says Amaya had not appeared in more than a month due to an injury, an absence that likely reduced the organization’s immediate flexibility for the end of the regular season and the postseason push. Minor-league decisions are often driven by health and availability as much as by past production, especially when teams are trying to balance playing time for prospects with the needs of depth.

Amaya’s situation also reflects a common late-summer pattern in professional baseball. When players are sidelined, organizations frequently reassess who can contribute in the remaining weeks, particularly for affiliates that may be playing meaningful games in September. Even a productive hitter can become a difficult fit if an injury limits his ability to play regularly, run, and train at full speed.

Beyond the Diamondbacks’ move, the same transactions roundup references additional minor transactions involving other names across baseball, including Conley, Arroyo and Hartwig. Because the public transaction summary provided here is primarily framed as a “catching up” list rather than a detailed team-by-team statement, the specific nature of each of those other entries (such as whether a player was released, assigned, or transferred) should be verified against the underlying MLB transactions log or team releases before being treated as complete information.

For the Diamondbacks, this update is best viewed as a roster housekeeping move and as a reminder that the organization’s organizational depth will continue to be in flux through the final stretch. The practical impact is primarily felt at the Triple-A and Double-A levels, where roster spots tighten around playing-time plans and where organizations look for healthy options who can keep producing while the calendar turns.

For Amaya, the release opens a path familiar to many minor leaguers: the chance to latch on elsewhere, potentially to resume at-bats and rebuild rhythm after an extended injury absence. His measurable offensive line at Reno, combined with the fact that the interruption was attributed to an injury rather than a prolonged performance slide, could influence how other clubs evaluate his next opportunity.

What to watch next is whether Reno or Arizona’s wider system quickly replaces Amaya’s role with a similar type of bat, and whether the other transactions items in the roundup resolve into confirmed moves in the official MLB transaction record. Those follow-ups will clarify how teams are reshaping depth as they head into the homestretch. If additional details emerge about the nature and timeline of Amaya’s injury, it will also shape how quickly any new team can deploy him.
