When Warren G took over the Wrigley Field press box Friday, Chicago Cubs fans heard the greatest four words they’ll hear all season outside of “your World Champion Cubs”.

“Cubbies fans…mount up!”

It all went south after that.

Yup. The “Regulator” himself botched “Take Me Out to the Ballgame” and fans both at the ballpark and online let him know all about it.

The Grammy-nominated rap artist took the criticism in stride, however. Instead of dwelling on his misstep during the seventh inning stretch, Warren G pointed out how good his ceremonial first pitch was.

He’d then show his admiration for the Windy City.

Mount up.
