Dodgers unearth a left-handed flamethrower with a wicked slider. Can he harness his electric stuff and polish his command for next season?

The Los Angeles Dodgers have built a reputation for identifying and refining high-upside pitching talent, and left-hander Adam Serwinowski fits squarely into that mold.

Acquired in a midseason trade last July, the 21-year-old immediately became one of the more intriguing arms in the organization thanks to a rare blend of velocity, movement, and physical projection.

Serwinowski’s fastball is the headliner. The pitch has already touched triple digits, an uncommon trait for a left-handed pitcher, and it plays even faster due to his 6-foot-5 frame and impressive extension toward the plate.

Hitters often have little time to react, particularly when the fastball is paired with his high-spin slider, a true swing-and-miss offering that flashes plus potential. The combination gives Serwinowski the foundation of a pitcher who can overwhelm hitters when everything is in sync.

Adding to the challenge for opposing batters is Serwinowski’s delivery. His motion features some deception and timing elements that make it difficult to pick up the ball early, further enhancing the effectiveness of his raw stuff.

That same delivery, however, contributes to the primary concern in his profile: command. Throughout his minor league career, Serwinowski has struggled to consistently locate his pitches, leading to elevated walk rates and shorter outings.

After joining the Dodgers organization, there were signs of progress. His walk rate showed a modest improvement over the final months of the season, an encouraging indicator that mechanical tweaks or a more structured developmental plan may already be paying dividends.

Still, further refinement is necessary, especially as he continues to climb the upper levels of the minor leagues where mistakes are punished more frequently.

Another key area of development is Serwinowski’s changeup. While his fastball and slider form a powerful two-pitch mix, the changeup remains a fringy offering.

If he can improve its consistency and effectiveness, it would give him a legitimate third pitch and significantly strengthen his case as a long-term starter rather than a bullpen conversion.

Fortunately for Serwinowski, the Dodgers provide an ideal environment for patient development. The organization boasts significant pitching depth, allowing them to avoid rushing him while focusing on incremental improvements.

With no need to protect him from the Rule 5 Draft for another year, Los Angeles can prioritize long-term growth over immediate results.

If Serwinowski takes meaningful steps forward with his command and changeup in 2026, his elite velocity and bat-missing slider could elevate him into one of the Dodgers’ most exciting pitching prospects and potentially a future fixture in their rotation.
