Phillies place right-hander Brad Keller on IL with right forearm tendinitis, recall Max Lazar

Philadelphia moved quickly to address a sudden bullpen concern Tuesday, placing right-handed pitcher Brad Keller on the 15-day injured list with right forearm tendinitis. The move was made prior to the Phillies’ game against the Miami Marlins and was retroactive to Sunday, meaning Keller’s IL clock began earlier than the announcement night.

Keller’s role has been central to the Phillies’ late-inning plans. In the team’s bullpen structure, he has served as a high-leverage, closing-type option, often called on when Philadelphia needs outs to protect narrow leads. With Keller sidelined, the club will have to redistribute those innings across the rest of its relief corps.

The Phillies’ roster decision accompanied Keller’s placement. To fill the active roster spot created by the IL move, Philadelphia recalled right-handed pitcher Max Lazar from Triple-A Lehigh Valley. The recall indicates that Lazar will be available in the immediate rotation of bullpen usage rather than waiting for a later call-up window.

For Philadelphia, the practical impact starts right away, because the IL move was effective beginning Sunday and the lineup changes typically affect who can pitch in consecutive games. Tendinitis injuries, even when they do not immediately force a longer absence, can alter how teams manage pitch counts, bullpen sessions, and the timing of call-ups, especially for relievers who rely on repeatable mechanics and fast recovery.

While the Phillies did not provide additional specifics beyond the diagnosis of right forearm tendinitis, the decision to place Keller on the 15-day IL indicates the team is treating the issue as significant enough to require a formal rest and evaluation period. In MLB roster management, that baseline IL designation also helps a club preserve roster flexibility while it monitors how the forearm responds.

The immediate focus in games against the Marlins and beyond will be on how Philadelphia reshapes late-inning usage. With Keller out, the Phillies’ manager will need to determine which available relievers can handle the highest leverage situations and whether Lazar’s first appearances come in lower-leverage matchups or in higher-leverage roles based on trust and recent workload.

Max Lazar’s activation from Triple-A introduces a fresh arm into the bullpen mix, but the extent of his role will likely depend on how quickly the Phillies can manage the remaining relief pitchers. The next few appearances will provide the clearest picture of how much responsibility Lazar assumes and which bullpen arms take on the innings Keller previously handled.
