Strong, square shoulders, strong arms and muscular forearms. Thick lower half, big thighs, strong base. There’s potential for bad weight here so he’ll have to keep up the conditioning.
Mechanics: Sets up with a slightly open stance and his hands away from his body and around ear level.

Has pre swing noise before he loads up, gets quiet when it’s time to swing. Plus bat speed. Leaks with the front side, swing can get out of sequence. Swing plane is power driven at present which will hurt the contact rate. Selectively aggressive, gets good extension at the plate. Can’t get hands around on FB on the inner half at present but has the wrist strength and bat speed to eventually catch up to velo in.
Plus-plus raw power, will play down to plus due to contact limiting in-game utility. Leveraged swing, creates good back spin on the ball. Power is pull oriented at present but natural strength and plus bat speed lend hope that opposite field power will come.
Deliberate runner, runs like he’s angry at the ground. Won’t be a factor on the base paths, has enough speed for a corner outfield spot. Will lose speed as he fills out.
Bad first step, below average reads in the field, range will play to fringe average.
Plus arm strength, ball has good carry and it skips hard when he two hops it in. At present the accuracy is below average.
Alex Jackson is struggling with an aggressive assignment to the Midwest league. In my viewing Jackson was cheating to get to the fastball in which left him vulnerable to soft stuff away. While that was concerning I also saw Jackson sting some balls down and in and put good backspin on the ball on a few flyouts. Jackson is a very raw product at present and his skillset is more promise than material but I think the promise is there. Jackson has the batspeed to figure out how to cover the inner half and he has a dream power-hitter’s frame. The work in the field isn’t anything to write home about but he can get to acceptable defense for a right fielder if the arm accuracy improves and he starts reading the ball better off the bat.
