Yankees Add Reliever John Schreiber Ahead of Postseason Roster Deadline

Core Event
The New York Yankees claimed right-hander John Schreiber off waivers from the Kansas City Royals on Monday, the final day teams could add players to the 40-man roster for postseason eligibility. The move makes Schreiber eligible for the Yankees’ September roster, and the club will assume roughly $600,000 of the $3.715 million salary he is owed for the remainder of the 2026 season.
Background & Context
Aaron Boone, the Yankees’ manager, has said he has been holding “open tryouts” in the bullpen because the reliever corps has been overworked and plagued by injuries. Recent setbacks include a partially torn ulnar collateral ligament for right-hander Fernando Cruz, forearm strain for left-hander Ryan Weathers, and other ailments to depth pieces Kervin Castro and Angel Chivilli.
In response, the Yankees have been active in the waiver market and free-agent arena. Over the past two weeks they added veteran right-handers Michael Fulmer, Justin Topa and Eli Morgan, while also recalling starter-turned-reliever Luis Gil and keeping Clarke Schmidt on a rehab assignment. The claim of Schreiber follows the designation of Justin Topa for assignment, opening a roster spot.
Data & Statistics
- 2026 season with Kansas City: 3.65 ERA in 55 appearances (49.1 innings).
- Split performance: right-handed batters hit .414 OPS against him; left-handed batters posted a 1.024 OPS. The New York Post reported right-handers hit .143 average and .414 OPS, while left-handers hit .326 average and 1.024 OPS.
- Ground-ball rate: 45.4 %.
- Strikeout rate: 18 % of batters.
- Walk rate: 11 %.
- Fielding-independent pitching (FIP): 4.87.
These metrics suggest a respectable ERA that is partly supported by a low .248 batting average on balls in play, despite modest strikeout and walk numbers.
Official Statements & Responses
Aaron Boone explained that the bullpen “has been overworked,” prompting the team to seek additional arms. The organization indicated that the waiver claim does not require a corresponding 40-man roster move because two roster spots are open and the active roster will expand from 26 to 28 players on Tuesday.
The Yankees’ front office has highlighted past success with late-season bullpen acquisitions—such as Paul Blackburn, Tim Hill and Luke Weaver—suggesting optimism that Schreiber could follow a similar trajectory.
Conflicting Reports & Gaps
Sources differ on Schreiber’s performance against right-handed hitters: ESPN cites a .414 OPS allowed, while the New York Post notes a .143 batting average and the same .414 OPS. Both agree on the 1.024 OPS allowed to left-handed batters. No source provides a definitive projection of Schreiber’s role or expected innings for the remainder of the season.
Why It Matters
Adding Schreiber gives the Yankees a 14th pitcher for the upcoming three-game series against the Angels and bolsters a bullpen that has logged heavy usage—Brent Headrick entered the week with an MLB-leading 70 appearances. If Schreiber can replicate his right-handed splits, he could provide a low-risk option for high-leverage situations as New York positions itself for a postseason run.
What’s Next
The Yankees must retain Schreiber on the roster through the deadline to keep him postseason-eligible. The expanded active roster will be in effect starting Tuesday, allowing the team to integrate Schreiber without designating another player.
