Chicago Cubs
Brad Wieck has thrown 1,237 pitches that have been tracked by the PITCHf/x system between 2018 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Fourseam Fastball (86mph) and Curve (68mph), also mixing in a Splitter (80mph). He also rarely throws a Change (80mph).
In 2024, compared to other LHP:
Their fourseam fastball comes in below hitting speed and has much less armside movement than typical. Their curve has an exceptional bite, comes in below hitting speed, generates an extremely high number of swings & misses compared to other pitchers' curves, results in somewhat more flyballs compared to other pitchers' curves and has slight glove-side movement. Their splitter comes in below hitting speed, generates an extremely high number of swings & misses compared to other pitchers' splitters, has surprising cut action, is an extreme flyball pitch compared to other pitchers' splitters and has some natural sink to it. Their change (take this with a grain of salt because they've only thrown 1 of them in 2024) generates an extremely high number of swings & misses compared to other pitchers' changeups, has surprising cut action, is an extreme flyball pitch compared to other pitchers' changeups, has slightly below average velo and has some natural sink to it.
