Jonathan Loáisiga signs minor‑league deal with Diamondbacks, gets spring training invite

Jonathan Loáisiga, a right‑hander who rose through the New York Yankees system, agreed to a minor‑league contract with the Arizona Diamondbacks that includes an invitation to major league spring training. The move, announced Jan. 13, 2026, is a low-cost, high-upside addition to Arizona’s relief picture that keeps the club’s 40-man roster flexible.

Loáisiga, 31, flashed high upside when healthy. His best season came in 2021, when he posted a sub‑2.20 ERA across more than 70 innings, showing late-inning potential and strikeout ability that made him a frequent option out of the Yankees bullpen. That peak, however, has been interrupted by elbow procedures and other injuries in recent seasons; his workload has been limited since 2023 as he has worked back toward full strength.

The deal is expressly structured to let Loáisiga compete for roles in spring without immediately costing Arizona a 40-man spot. The contract is a straight minor‑league agreement that brings him into big-league camp on a camp invite; as the club put it in the announcement, it is a "minor‑league deal with an invitation to spring training." If he proves healthy and effective, the D-backs can add him to the roster later or use him as organizational depth while maintaining roster flexibility during the offseason and early spring.

For Triple-A and local fans, the signing matters on several levels. For the D-backs’ pitching depth chart it creates a veteran arm who can be optioned to the minors for workload management and to provide experienced relief innings at the Triple-A level if needed. For fans and fantasy players tracking bounce-back candidates, Loáisiga is a clear watch, spring training will reveal whether his velocity, command and durability have returned to the form that made him an intriguing late-inning candidate in 2021.

Practical evaluation hinges on health and usage. Monitor his spring appearances for pitch velocity, inning limits and any signs of recurring elbow trouble. The club’s choice to start him on a minor‑league agreement signals caution but also a willingness to gamble on a veteran with a high ceiling if he can remain available.

What comes next is straightforward: Loáisiga will have the chance to earn a roster spot in Arizona’s camp or begin the season as experienced depth in the minors. For followers of Triple-A rosters and D-backs bullpen construction, his spring will be the pulse check, a successful camp could turn an inexpensive pickup into a late-inning option, while setbacks would keep him on the organization’s depth chart as it manages innings and injury risk.
