When did Hideo Nomo pitch both games of a doubleheader?

Answer 1

Nomo never pitched both games of an MLB double header. After many of his starts, the record shows notation 2. The 2 refers to the 2nd game that day, not both games. But no two of the 323 lifetime MLB games did this power pitcher throw in both ends of a double header.

But he may have done so in Japan - maybe the rumor started there?
