Detroit Tigers
Although they have not thrown an MLB pitch in 2024, Luke Putkonen threw 832 pitches that were tracked by the PITCHf/x system between 2012 and 2014, all of them occuring in the MLB Regular Season. In 2014, they relied primarily on their Fourseam Fastball (93mph) and Curve using a Knuckle Curve grip (79mph), also mixing in a Splitter (85mph).
In 2014, compared to other RHP:
Their fourseam fastball is an extreme flyball pitch compared to other pitchers' fourseamers, generates fewer whiffs/swing compared to other pitchers' fourseamers, has some natural sinking action, has essentially average velo and has slight armside run. Their curve using a knuckle curve grip (take this with a grain of salt because they've only thrown 14 of them in 2014) is basically never swung at and missed 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. Their splitter (take this with a grain of salt because they've only thrown 7 of them in 2014) generates an extremely high number of swings & misses compared to other pitchers' splitters, is an extreme flyball pitch compared to other pitchers' splitters and has some natural sink to it.
