Nationals recall No. 12 prospect Luis Perales to strengthen bullpen

The Washington Nationals have called up Luis Perales, a 23-year-old right-hander who enters the big leagues as the organization’s No. 12 prospect. Perales’ promotion comes with a clear near-term assignment, he is expected to pitch in the Nationals’ bullpen, while the longer-term picture remains bigger: the organization sees a potential pathway to starting as soon as next season.

According to the Nationals’ announcement, the recall places Perales among the latest wave of prospects getting major-league exposure. For a pitcher whose prospect standing gives him runway but not certainty, the first order of business is performance and usability. In-season calls often function as extended tryouts, with managers and coaches looking not only at whether a pitcher can retire batters, but also at how comfortably he fits the team’s plans for workload, matchups, and late-inning leverage.

Perales is arriving from Triple-A Rochester, a step that usually demands a different kind of preparation than the majors. The administrative jump includes a faster pace between at-bats, more detailed scouting on repeated opponents, and a more precise demand for situational command. The Nationals’ framing of Perales as a “could factor” type underscores that the organization views him as close, but still mid-development, with the bullpen call serving as an on-ramp.

The organization’s own description also highlights Perales’ mindset. The report says he is embracing the chance to pitch out of the bullpen and “get his feet wet” in the major leagues. That matters because for many pitchers transitioning from starter profiles in the minors to relief roles in the majors, the mental rhythm changes. Bullpen outings require quick resets and a shorter, more repetitive preparation cycle, even when the overall goal remains the same: command the strike zone, use secondary pitches in the right counts, and make pitches that travel well under pressure.

While Perales is being used as a bullpen piece for now, the Nationals’ note leaves the door open for an expanded role later. The same report indicates that he “could factor into the Nationals’ starting rotation as soon as next season.” That projection is not a promise, but it does report organizational belief that his talent can translate beyond relief. Whether that happens typically depends on durability, the quality of his third or fourth look through an order, and whether his pitching style can be stretched to starter workload without losing effectiveness.

For Washington, the immediate value of the call is depth. A bullpen is rarely built on one pitcher, it is built through reliable options who can cover different innings and different hitters. A young right-hander promoted at this stage of the season gives the Nationals additional flexibility, especially when games hinge on late leverage. The larger value is evaluation, because a major-league sample can quickly clarify what needs refinement, whether it is pitch usage patterns, command consistency, or handling hitters who see the pitcher the second time in a game.

What to watch next is straightforward. If Perales earns repeated opportunities, it suggests the team sees stable command and a pitch mix that works in high-leverage innings. If his innings rise beyond brief stints, the Nationals may be preparing a bigger role, potentially including longer relief or a later step toward a starter profile. Either way, his first major-league month will likely be less about highlight moments and more about whether he can execute a plan against MLB hitters.
