3/1/15 - Long projectable frame, 6-foot-5, 175-pound left-handed pitcher, prototypical pitchers frame, long legs and arms, plenty of room to fill, good ceiling. Fluid delivery works with tempo and direction, little effort, good athleticism, controls body well for size. Arm action is loose, has length, average arm speed, high ¾ slot, comes out of hand with ease. Fastball runs to arm side, sat mostly 77 mph. Threw two breaking balls, curveball has better feel and action, 1/7 plane, 63-65 mph. Slider backs up occasionally, ranged from 61-67 mph. Very projectable left-handed arm, easy delivery with athleticism, high follow in Wisconsin’s 2017 class.

10/25/14 - Projectable left-handed pitcher, long thin frame, body has huge upside, extra-large hands, 6-foot-4, 160-pounds. Tall and fall delivery with smooth/deliberate repeatable rhythm, occasionally gets head off line, creates good downhill angle, easy effort, squared landing. Arm action is long and clean, loose free and easy, projects for more, high ¾ slot. Fastball has sink, works downhill, showed feel for the zone. 74-75 mph. Throws two breaking balls. Curveball has more 12/6 shape, showed decent feel, 62-64 mph, can be more aggressive. Slider has flatter action, 62-63 mph, 2/8 shape, showed feel. Looks to project better with curveball, creates a better angle and matches fastball window better.

Summer 2020: After a fabulous 2019 summer season for the Booyah when he went 3-2 with a 1.84 ERA in 39 IP with 46 strikeouts, Mahoney returned to Green Bay this summer looking to dominate once again. Although that didn’t happen statistically (1-3, 4.02 ERA, 31.1 IP, 18 BB, 27 SO), he looked strong during a mid-July outing with an 88-91 mph fastball and two quality secondary offerings. His late tailing heater spun in the 2230-2350 rpm range with some weight to it when down in the zone. He mixed in an 84 mph change with good bottom, spinning near 2000 rpm and a slurvy 75-76 mph breaking ball with consistent 2500 rpm spin rates. The 6-foot-8, 235-pound left-hander returns to Milwaukee for his covid-junior season where he could become a later round pick next June.

9/23/19: Junior, 6-foot-8, 215 pound lefty with a highly projectable frame. A lean, high-waisted athlete who’s only added muscle to his lower half over the last year or so. His long levers have taken some time to harness, but it appears he’s turned a corner. After striking out 38 batters in 36.1 innings last spring, walks were still heavily attached to his game. But, a summer stint in Green Bay (Northwoods League) seems to have helped Mahoney better grapple with his command. He pitched 39 innings over the summer with 46 Ks and 16 walks with an impressive 1.84 ERA. On this look, he proved that his time with the Booyahs was no fluke, after punching out six of the seven batters he faced on Friday. He walked one, but otherwise didn’t allow a single barrel, fair or foul, and was pounding the zone. Sat 89-92 mph in his first inning from a closed landing, three-quarter slot, which helps add deception to his already imposing presence on the mound. The separators here are the feel for his offspeed; a sweeping slider, 74-76 mph, that was earning chases, and he showed a couple changeups, 82 mph, straight with some slight fade. His size, velocity, ease of effort, and newfound control could help him gain some steam in the pro scouting community come June.
