On mound at Tokyo Dome, Taneichi, wearing number 26, leaped with joy. In the 7th inning, with the score tied 5-5, he made his WBC debut as the third pitcher, mixing his fastest 156 km/h fastball with a fork strike out a spectacular display. His fiery 15 pitches led to three runs for his teammates in the 7th inning, securing their first WBC win.

I overcame the ordeal. At the beginning of the Miyazaki training camp that started on February 14th, he injured his lower body during practice. He continued to pitch in bullpen, but did not make any actual appearances. In order to face the actual race in the best condition, I worked hard to recover and made it in time. The 156 kg fastball he threw is proof of a complete revival. Coach Ibata praised, "It's my first appearance, but he pulled the flow with a pretty good ball, and I'm satisfied."

The right-handed pitcher, who has publicly stated his dream of playing in the major leagues in the future, sees the WBC as "a turning point in my life." He made a strong impression with a perfect pitch, which served as his calling card, showcasing his "TANEICHI" (a term referring to a strong, determined pitcher).
