Mason Montgomery’s late-summer climb puts Pirates’ bullpen back in focus

PITTSBURGH, Aug. 26. Mason Montgomery has moved closer to the role the Pirates have needed most late in games, with Yahoo Sports reporting that he is “emerging into closer” territory for Pittsburgh. The discussion around the righthander is rooted in the way his pitches have played in recent looks, highlighted by a 101 mph fastball and breaking pitches described as strong, a combination that can change how late innings are managed.

For a team that has spent a significant portion of the season chasing the right late-game answers, the bullpen is not a side story. Yahoo Sports frames the Pirates bullpen as one of the main reasons a once promising season “turned on a dime” and became the most disappointing in the decade. Even without leaning on season-long numbers here, that characterization explains why the closer conversation carries added weight in Pittsburgh, where one or two late-inning swings can reshape a team’s month quickly.

Montgomery’s path into this discussion follows the common MLB blueprint for closers, which is less about a title and more about repeated trust. A ninth-inning option is typically earned through the ability to throw premium pitches under pressure, and the reporting points directly to what he brings when the margin tightens: velocity up around triple digits, plus a breaking pitch arsenal capable of producing different looks than a straight fastball diet.

That pitch design matters for bullpen usage. A closer role can force other relief patterns on a staff, affecting how long setup arms can hold leverage, how managers sequence matchups, and how frequently the back end can be used on consecutive days. If Montgomery is truly moving into that role, it would give Pittsburgh a clearer high-leverage identity, something that can reduce the constant reshuffling that has historically hurt teams trying to stabilize the final outs.

At the same time, it is important to keep the scope of what is actually confirmed. The account describes Montgomery’s emergence and the bullpen’s struggles, but the reporting does not, in the material available here, provide a full statistical ledger, an official depth-chart change, or explicit confirmation of a permanent assignment. In August, roles can still be fluid, especially in a season where performance has dictated frequent adjustments.

The Pirates also face the broader roster question that comes with any closer development. The closer slot is rarely created in isolation, it is reinforced by the rest of the bullpen offering reliable innings behind him. Montgomery’s rise, then, is best understood as both a player-development storyline and a bullpen-structure storyline, tied to how the Pirates plan to finish games the rest of the way and what they can carry forward into the offseason.

Going forward, the key items to watch are straightforward: whether Montgomery continues to be entrusted with the most critical late situations, how his pitch execution holds up when hitters know he is the option, and whether the staff around him can convert his late-inning presence into consistent results. If he becomes the stable leverage arm the Pirates have lacked, it will not only change individual outcomes, it will alter how the entire bullpen is built to win close games.
