Caleb Thielbar has thrown 6,250 pitches that have been tracked by the PITCHf/x system between 2013 and 2025, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (93mph), Slider (84mph) and Curve (76mph).
In 2025, compared to other LHP:
Their fourseam fastball is straight as an arrow, has slightly above average velo and has some added backspin. Their slider sweeps across the zone, generates fewer whiffs/swing compared to other pitchers' sliders, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their curve has an exceptional bite and has slight glove-side movement.
