Chicago Cubs
Caleb Thielbar has thrown 6,799 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 (86mph) and Curve (76mph). He also rarely throws a Splitter (82mph).
In 2026, compared to other LHP:
Their fourseam fastball is an extreme flyball pitch compared to other pitchers' fourseamers, has much less armside movement than typical, has slightly above average velo and has some added backspin. Their slider has short glove-side cut and is much harder than usual. Their curve has an exceptional bite, is basically never swung at and missed compared to other pitchers' curves and is an extreme flyball pitch 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.
