    Alderman ranked as the No. 374 prospect in the 2020 class out of high school as a two-way player with a low-90s fastball on the mound and plus raw power with some feel for the barrel as a hitter. A hitter only now, Alderman had the best season of his career in 2023, when he hit .376/.440/.709 with 19 home runs, 14 doubles and some of the best pure raw power in the class. The 6-foot-3, 250-pound righthanded hitter has light-tower power and hits massive home runs to the pull side, with a 90th percentile exit velocity of more than 114 mph. He has a low handset in his setup, with a crouched stance and relatively simple operation overall, but his power comes with exceptional chase and miss rates, though his overall 2023 strikeout rate, 16.9%, was respectable. It’s a solidly power-over-hit offensive profile and he’ll need to find a way to become more selective, or make more contact, at the next level. Alderman’s defensive profile is an interesting one. He’s a good athlete who has spent most of his time in the corner outfield spots and some time at first base, but he has also played a bit of catcher as well. Teams would love to get his raw power behind the plate, but he will need to dramatically improve his actions, hands, exchange and footwork to make that happen. He’s most likely a corner outfield/first baseman in pro ball.
