Tampa Bay Rays
Although they have not thrown an MLB pitch in 2024, Jeff Niemann threw 8,722 pitches that were tracked by the PITCHf/x system between 2008 and 2012, including pitches thrown in the MLB Regular Season and Spring Training. In 2012, they relied primarily on their Sinker (91mph) and Fourseam Fastball (90mph), also mixing in a Curve (77mph), Slider (86mph) and Splitter (83mph).
In 2012, compared to other RHP:
Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers and has surprisingly little armside run. Their fourseam fastball is straight as an arrow, generates a high number of swings & misses compared to other pitchers' fourseamers, has some natural sinking action and has slightly below average velo. Their curve has an exceptional bite and generates fewer whiffs/swing compared to other pitchers' curves. Their slider is a prototypical pitch with few remarkable qualities. Their splitter results in more flyballs compared to other pitchers' splitters, has movement that suggests a lot of backspin and has slightly below average velo.
