Scouting Report
Pre-2025 Scouting Report
The Slovakian-Canadian came over in the controversial Teoscar Hernandez trade, but his performance in the minors since joining the Blue Jays is not one of the reasons for that controversy. The undersized lefty who attended Vauxhall Academy in Alberta has struggled with his health and his command ever since being drafted by the Seattle Mariners in the seventh round of the 2019 draft. However, since joining the Blue Jays organization, Macko has steadily lowered his walk rate from about 12.0% with the Mariners, to 10.8% in 2023, and then in 2024 lowered it again to 9.0%. He also threw career highs in innings pitched with 86.0 in 2023 and then 93.1 in 2024. That being said, his command is still fringe-average at best, and he was shelved for six weeks for a forearm strain, showing that his injury issues weren’t fully behind him.
Macko has been quite successful in his professional career at striking hitters out, with a greater than 25% strikeout rate at every level he’s pitched at (other than the three innings he pitched in his debut with the Buffalo Bisons). Macko is able to rack up those strikeouts with his solid secondary pitches, the best one being his big loopy curveball, which he throws in the mid-70s, which comes equipped with 14.8 inches of induced vertical break as well as 7.6 inches of arm side horizontal break that makes hitters look foolish swinging at it. However, hitters rarely did so because the pitch is easy to identify out of the hand with its shape and velocity.
The slider is the secondary pitch he throws the most, which he tosses in the low-80s. It's more of a pitch he can locate in the zone more often and helps bridge the gap between his fastball and slow curveball. Macko’s fastball velocity is pretty mediocre, actually regressing a bit since last year where he used to sit 93-95 mph (now in the 91-93 mph range), but he has a deceptive delivery and his fastball had a 15.3 iVB in his short appearance in Triple-A Buffalo. It also has 7.9 inches of run as well, which helps it play up. He still can touch up to 95 mph, but that comes fewer and farther between than years past. Lastly, his changeup has a nice shape as well, with 15.9 inches of fading action, but he isn’t as consistent with it compared to his other offerings.
This will be Macko’s second year on the Blue Jays’ 40-man roster, and now that he’s pitched decently in Double-A New Hampshire, he’s looking to continue his success in Triple-A Buffalo. His fringy velocity and average command probably limits his ceiling to a back-end rotation starter, but he’ll be a part of the limited starting pitching depth for the Jays in 2025, behind Jake Bloss and maybe even Easton Lucas and Adam Kloffenstein.
