Winnipeg Free Press reports Yoshida has left hamstring tightness. Yahoo Sports describes the injury as occurring as he slides into second base, without specifying the exact diagnosis. Together, the accounts indicate the injury happens during base running and forces an early departure from the game.

The sources do not provide additional details on the severity of the issue, the results of any medical evaluation, or whether he will miss subsequent games. Further updates would depend on team medical updates and any official status announcement.
