The game is paused due to the rain. Mukai stretches in his dugout, Furuya looks spaced out, and Sawamura is pitching in the bullpen. The game resumes, and Miyuki immediately gets a double. However, Mukai is keeping it cool on the mound.
I understand the substitution, 
given how Furuya is pitching.
Ich verstehe den Wechsel,
so wie Furuya jetzt drauf ist.
Capisco la sostituzione,
visto come sta giocando Furuya.
Dá para entender a troca, 
vendo como o Furuya está.
