Forkin did not leave the game, however, and on the next pitch, she struck out.
Canada's Natalie Wideman had a 1-2 count when she stepped up to the plate for the fourth time on Friday. Teammate Erika Polidori was waiting at second base.
With the game against Japan tied at 1, Wideman delivered the walk-off double in the bottom of the seventh inning to give the Canadians a 2-1 win over Japan.
Japan tied the game in the top of the fifth, after Sonoka Kuniyoshi scored on error by the right fielder. Kuniyoshi singled during her at-bat, stole second base while Yuka Ichiguchi was at bat, and advanced to third when Ichiguchi singled.
Between the two teams, nine players were left on base during the game, and neither of the starting pitchers allowed more than four hits.
