Cape Cod- Has been the most consistent producer in the Harbor Hawks' lineup, including two 3-for-5 nights in my final two viewings and another in Aaron Fitt's lone viewing. The Missouri infielder hits most of his hard contact to pull and has a swing geared to those ends, driving balls well on the inner half while showing slightly softer contact and finding fewer barrels away. The bat speed is average and he can struggle at times with tracking and pitch-ID, which combined with his middle-in approach can expose him to soft stuff away. His range and hands at third are limited but adequate at the collegiate ranks, and he has plenty of arm for the throws needed at the hot corner. There's enough pop in the bat to make Mann an intriguing follow as a potential three-outcome stick, but the strikeout rates (39% on the season and 32% thus far on the Cape) will need to come down in order for him to impact boards come next summer.


The lefty hitter lit up the Arizona Wildcats during a day game on Sunday, looking more like our No. 185 ranked prospect than what he showed the two previous evenings. Whether it was poor night vision or he was too amped up for the evening contests, Mann left Frisco on Sunday with some confidence. Coming into the 2021 season as a potential corner bat who could be considered around the 5th round, Mann struggled mightily during the first two games of the Classic (0-for-5 with five strikeouts) looking lost at the plate while chasing numerous fastballs out of the zone. On Sunday he turned things around in a big way, ambushing a first pitch 95 mph heater from Wildcats’ starter TJ Nichols. The ball left the yard in a hurry, landing in the pool well beyond the right field fence. His next at-bat he turned around another offering for a double into the right center field gap.


The No. 1 ranked prep prospect from Missouri for the 2018 draft, Mann has mashed this fall after a shortened 2020 spring season which saw him strike out 21 times in 40 at-bats. After an all-star summer in the CarShield Collegiate League, he has smoothed out his swing. With consistent solid contact and exit velocities during this recent scrimmage ranging from 99 mph on an oppo taco to 106.8 mph on a line drive single to his pull side, he can now get to his real power to all fields. Defensively, Mann shows good reactions and does well on body control, slow rollers. He has average hands and average arm strength with his arm playing up a bit due to his quick catch/release. He has a chance to become near average ML third baseman with average range. Mann projects as a mid-Day Two prospect who could jump into the top 4-5 rounds with a big spring at the plate.

7/11/17 - Missouri commit. Currently ranked No. 1 in the Missouri Class of 2018 and No. 128 in the PBR Overalls. 6-foot-2, 205-pound right-handed pitcher with a strong, athletic frame.
