Blue Jays Reach Agreement With 23-Year-Old Japanese Righty Tomoya Kinjo

The deal adds a high-velocity development arm to Toronto’s system during the international signing window.

Overview

  • Multiple outlets reported Monday that Tomoya Kinjo agreed to join Toronto pending a physical, citing MLB reporter Francys Romero.
  • Kinjo, 23, tops out at 97 mph and also throws a changeup, curveball, and sinker, according to the reports.
  • The agreement falls under MLB’s international signing period, which runs through December 15 and typically sends players into the minors first.
  • He is expected to open in the Blue Jays’ farm system rather than fill the injury-hit major-league rotation right away.
  • Kinjo pitched in 2025 for Japan’s independent Kochi Fighting Dogs and in the Japan Winter League and has shared videos chasing a 100 mph fastball, with contract terms not disclosed.
