The 13-year-old Motegi was so happy as he rounded the bases that he jumped into the arms of his third-base coach down the line before even reaching the plate.
Both teams flashed big-league defense and dominated from the mound. Japan and Taiwan pitching combined for 30 strikeouts.
Japan frittered away other chances late to win, including the eighth with the bases loaded and one out. But Taiwan reliever Cheng-Kai Hu came on to strike out the next two batters to get out of the jam.
Motegi saved the night's biggest hit for the ninth.
