うちの へちあいの かわりに 4ばん うたねえか？
Another one. This one is supposed to be from a baseball game...
This should be:
"You wanna bat fourth instead of our guy Hechiai?"
As far as I can tell, the name Hechiai is a play on the name Ochiai (落合). The word へち means "sponge" or "loofah". If I'm not mistaken, this is a reference to a player in ファミスタ baseball series (the Japanese version of RBI Baseball).
