Scouting Report
Updated May 19, 2026
Johnny King is a 19-year-old left-handed pitcher prospect for the Toronto Blue Jays, drafted in the 3rd round (95th overall) of the 2024 MLB Draft. Currently playing High-A ball in the Northwest League, King is the youngest player in the league but is dominating hitters significantly older than him. He has posted a 1.04 ERA, 1.17 WHIP, and 25:13 K:BB ratio through 17.1 innings over six starts. King features a mid-90s fastball (touching 96 mph) with carry from a low three-quarters arm slot, a nasty curveball that generates whiffs, and a developing changeup. MLB.com tags him as the Blue Jays' hottest pitching prospect. The Blue Jays are building him up slowly given his age, with a maximum of four innings per outing so far. Control remains a concern, and he will need to develop a reliable third pitch to avoid a future in the bullpen.
