Gotham City Knights

From BR Bullpen

The Gotham City Knights are the team that represents Gotham City in the DC Universe MLB. Their team colors are black and yellow.

In the Elseworlds miniseries "Kingdom Come", the Gotham Knights are depicted as the winners of the final World Series before the MLB disbanded. This was in an alternate universe, so in the current DC continuity, the MLB and Gotham Knights still exist.
