"Macko has an interesting story, as he was born in Slovakia, eventually moved to Ireland and was raised there, before joining Vauxhall Academy in Alberta, playing alongside fellow Blue Jays' prospect Damiano Palmegiani. Macko was selected in the seventh round of the 2019 draft by the Mariners. The 6'0», 170 lbs left-handed pitcher made his professional debut that same season, posting a 3.09 ERA and 3.83 FIP in 23.1 innings pitched, with a 33 K% and 11.7 BB%."-Delaney
