The game was briefly held up ... and security apprehended Rose and Summer and escorted them from their seats.

Rose and Summer's accomplice, Kayla Lauren (also a model), claims the women were taken to police headquarters ... before being released.

Rose posted a letter she says she got from Major League Baseball ... that banned her from MLB events.

The letter, from baseball's V.P. of Security, says ... "On October 27, 2019, you attended World Series Game 5 at Nationals Park in Washington D.C. During the game, you violated the fan code of conduct by exposing yourself during the 7th inning, in order to promote your business."
