Chicago Cubs
Caleb Thielbar has thrown 7,261 pitches that have been tracked by the PITCHf/x system between 2013 and 2026, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2026, they have relied primarily on their Fourseam Fastball (93mph), Slider (85mph) and Curve (76mph). He also rarely throws a Splitter (82mph).
In 2026, compared to other LHP:
Their fourseam fastball generates a high number of swings & misses compared to other pitchers' fourseamers, has much less armside movement than typical, results in more flyballs compared to other pitchers' fourseamers and has slightly above average velo. Their slider has short glove-side cut, is much harder than usual and results in somewhat more flyballs compared to other pitchers' sliders. Their curve has an exceptional bite and results in somewhat more flyballs compared to other pitchers' curves. Their splitter (take this with a grain of salt because they've only thrown 6 of them in 2026) is basically never swung at and missed compared to other pitchers' splitters, has surprising cut action, is an extreme flyball pitch compared to other pitchers' splitters and has below average velo.
