Major League Baseball has indefinitely banned two women who flashed their chests on television during the seventh inning of Game 5 of the World Series on Sunday night.

MLB spokesman Michael Teevan told USA TODAY Sports that the league has "distributed a letter to the individuals in question, and the letter set forth an indefinite ban for each."

The league's letter informed the women that they violated the league's code of fan conduct by exposing themselves to "promote a business."

The women, identified as Shagmag founder Julia Rose and company brand executive Lauren Summer, claimed on social media to be promoting breast cancer awareness through the stunt. Both Rose and Summer shared their ban letters signed by MLB vice president for security and ballpark operations David Thomas over Twitter.

The women, wearing yellow shirts, were sitting just a few rows from the field behind home plate during an at-bat between Astros ace Gerrit Cole and Nationals first baseman Ryan Zimmerman.

The Astros went on to win Game 5 on Sunday 7-1 to take a 3-2 edge in the best-of-seven World Series.
