Ellwanger was a notable prospect before the 2023 draft and slipped due to signability concerns. The Nats took him in the 19th round, and he is their type of prep power arm. It's an intriguing combination of size, stuff, and refinement needed, particularly on the secondary pitches and with his control.

Ellwanger stands 6'5", 205, it's a lean frame with more strength to add. Even so, he can run his fastball up into the high 90s with good ride and armside run. There's a good curveball present too, an above-average pitch, with a slider and changeup that haven't proven to be as effective yet. Strike throwing has also been a challenge for Ellwanger at times. Despite too many free passes (13.5%), he's performed solidly in 2025. It's a 3.07 FIP and 33 K%. You'll need a drafting organization that knows what they're doing with pitchers, but the arm talent is considerable.
