Seattle Mariners
Although they have not thrown an MLB pitch in 2024, Joe Nelson threw 1,863 pitches that were tracked by the PITCHf/x system between 2008 and 2010, including pitches thrown in the MLB Regular Season and Spring Training. In 2010, they relied primarily on their Fourseam Fastball (88mph) and Change using a Vulcan Change grip (78mph). He also rarely threw a Curve (73mph).
In 2010, compared to other RHP:
Their fourseam fastball comes in below hitting speed, has heavy sinking action, results in more flyballs compared to other pitchers' fourseamers and has slight armside run. Their change using a vulcan change grip comes in below hitting speed, results in more flyballs compared to other pitchers' changeups and has some natural sink to it. Their curve (take this with a grain of salt because they've only thrown 5 of them in 2010) comes in below hitting speed, generates an extremely high number of swings & misses compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has a sharp downward bite and has slight glove-side movement.
