Boston Red Sox
Nick Pivetta has thrown 13,192 pitches that have been tracked by the PITCHf/x system between 2017 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they have relied primarily on their Fourseam Fastball (94mph) and Curve (77mph), also mixing in a Slider (86mph). He also rarely throws a Splitter (87mph) and Change (85mph).
In 2022, compared to other RHP:
His fourseam fastball has good "rising" action, has less armside movement than typical, has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. His curve has an exceptional bite and results in many more groundballs compared to other pitchers' curves. His slider is a prototypical pitch with few remarkable qualities. His splitter is an extreme flyball pitch compared to other pitchers' splitters, generates fewer whiffs/swing compared to other pitchers' splitters and is much firmer than usual. His change (take this with a grain of salt because he's only thrown 17 of them in 2022) generates fewer whiffs/swing compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has a lot of backspin.
