Pitching style
Rowen pitched with a submarine-style delivery.[35][36] Rowen threw three pitches: a two-seam fastball, a slider, and a changeup. He was compared to former submarine reliever Chad Bradford due to their low fastball velocity. Rowen's fastball topped out between 78–82 miles per hour (126–132 km/h).[37] In 2021, Rowen switched to an overhand pitching delivery.[38]
