Five runs in a single inning? That's not especially unusual. Or noteworthy.
It was how they scored their runs.
Four home runs in the inning. Including three in a row.
My favorite part of the screenshot are the names. It's kind of exactly how you would imagine an inning would go for the 2001 Royals, who had some serious thunder in the lineup, yet were surrounded by an underwhelming cast of supporting characters.
For perspective, Sweeney hit third. Meaning Joe Randa was cleanup. Seriously. With Sweeney, Dye, Ibanez and Beltran, Joe Randa was Tony Muser's choice for cleanup.
Now I'm just being another critical spirit.
