Kansas City Royals prospect L.P. Langevin is drawing attention for his unique fastball, which features an exceptional spin rate and unpredictable movement that leaves hitters baffled. The 23-year-old right-hander, a fourth-round pick from the 2024 MLB Draft, has struck out 70 of 151 batters faced with Quad City in 2026, allowing only 12 hits in just over 35 innings. However, his pitch command remains inconsistent, as he has issued 27 walks, hit 4 batters, and thrown 7 wild pitches, resulting in 12 earned runs despite his dominance on strikeouts.

Langevin’s fastball, averaging 92-95 mph and delivered from a low three-quarters to sidearm slot, can dart toward or away from hitters unpredictably due to its high spin. Though his raw talent is evident, he lacks a reliable secondary pitch and consistent control, limiting his overall effectiveness. Kansas City Royals Scouting Director Brian Bridges praises Langevin’s fierce competitiveness and willingness to learn but notes his limited exposure to analytics and refinement tools that could enhance his pitching.

Born in Quebec City, Canada, Langevin transitioned from hockey to baseball in high school and developed his pitching skills at Wabash Community College before making a strong showing at Louisiana-Lafayette in 2024. He signed for $597,500 after being chosen 105th overall in the draft, joining a lineage of notable players selected at that spot, including Cy Young winner Cliff Lee and Kansas City icon Bo Jackson. His collegiate success included 106 strikeouts and a solid 6-1 record, setting the stage for his professional development.

Langevin’s future in the majors depends heavily on his ability to master a dependable secondary pitch, like a changeup or breaking ball, to complement his electric fastball. Currently ranked 26th among Royals prospects, he shares similar developmental hurdles with fellow Royals pitcher Luinder Avila. The team remains patient with Langevin, who is known as a hardworking and coachable athlete, while other organizations could show interest in him as a trade asset pending improvements. His progress will determine if he evolves from a “wild thing” into a reliable major league reliever.
