The Blue Jays promoted King from High-A Vancouver to Double-A New Hampshire on Monday.
A third-round pick in the 2024 First-Year Player Draft, King established himself as one of the Blue Jays' top lower-level arms last season and has continued to dazzle in 2026. The 20-year-old lefty earned the bump up to New Hampshire after posting a 30.6 percent strikeout rate and 3.21 ERA over 84 innings at High-A.
