My point was an overly uppercut swing isn't going to result in that low a launch angle. Not unless he is somehow consistently topping the pitches, which seems pretty unlikely.
You are comparing Statcast's reading on one ball to Statcast's data on every ball Jackson's hit?
A launch angle of 4.4 degrees is extremely low, that's Vlad Jr in 2020 low.
It isn't just the money, they've got multiple guys that have done well in the minors vying for that roster spot. You going to keep them all in AAA for another season?
