Two Instagram models claimed Monday that they've been banned indefinitely from Major League Baseball stadiums after the pair exposed themselves -- on live TV -- during Sunday night’s World Series Game 5.

Footage, which swiftly made its way to social media, showed Houston Astros ace Gerrit Cole preparing to make a pitch in the bottom of the seventh when the two women – who were standing behind home plate at Nationals Park – lifted up their shirts to expose their breasts.

The stunt appeared to have no effect on Cole, who briefly paused, or the Astros, who went on beat the Washington Nationals, 7-1, and take a commanding 3-2 lead in the best of seven series.

“During the game, you violated the fan code of conduct by exposing yourself during the 7th inning, in order to promote a business,” reads a letter MLB’s vice president of security and ballpark operations allegedly sent to the two women following the game. One of them posted a pic of the letter on Twitter.
