Yoshitomo Tsutsugo was struck by a strange thought while playing for Samurai Japan during the 2017 World Baseball Classic.

There were pitch limits in effect during that tournament, which features professional players, adults from MLB, NPB and other leagues. Meanwhile at the high school level in Japan, children were being asked to throw with no such limits and seemingly little regard their bodies.

"The kids weren't being protected," Tsutsugo said on Friday morning at the Foreign Correspondents' Club of Japan. "I remember thinking that was strange."
