Dodgers Bring Reliever Jonathan Hernández Back to the Big Leagues, Creating a Bullpen Opening

The Los Angeles Dodgers have selected reliever Jonathan Hernández back onto the major league roster, a transaction that immediately changes the structure of their bullpen as they manage the demands of a long schedule. The move, announced Tuesday, also came with a roster off-ramp for starting depth, as Landon Knack was optioned to Triple-A Oklahoma City to open space.

In addition to selecting Hernández, the Dodgers optioned Knack to Triple-A Oklahoma City, according to the team’s procedural changes reported with the announcement. The immediate on-field implication is clear: Hernández returns to provide bullpen support, while the club has shifted Knack away from the active pitching group for the time being.

What remains to be clarified is how L.A. will address the 40-man roster accounting. The report notes that the Dodgers did not announce a corresponding 40-man roster move at the time the selection was made. That matters because MLB roster construction rules generally require balance on the 40-man between additions and removals, meaning another transaction may be forthcoming to complete the bookkeeping.

For the Dodgers, this kind of sequence is often about creating a workable bullpen mix and aligning innings with matchups. Hernández’s return suggests the club is prioritizing bullpen availability in the near term, while moving Knack to Triple-A indicates the organization is comfortable with him working outside the active rotation of pitchers for the moment.

The option to Oklahoma City also highlights how the Dodgers continue to manage pitching resources across levels. Optioning a player does not erase their usefulness, but it does place them in a position where their next call-up can be timed to need, rather than relying strictly on active-day roster limits.

There is one watch item for Dodgers followers: whether the team follows up with the additional roster move needed to keep the 40-man set compliant. Because Hernández’s selection is already on the surface, the missing piece is the matching 40-man move that would complete the transaction trail.

Beyond the roster mechanics, the broader competitive picture is that bullpen reliability has become even more central to postseason preparation in recent years. As the Dodgers handle late-season roster management, Hernández’s presence and the timing of Knack’s next major league opportunity could both influence how L.A. deploys its pitching staff in close games.
