Alize Cornet sparks criticism of sexist treatment at the US Open

US Open officials have been slammed as sexist after a chair umpire hit French tennis player Alize Cornet with a code violation because she took her shirt off briefly during a heat break.

Cornet was captured on video at the tournament Tuesday in New York as she walked back to the court for her match against Swedish player Johanna Larsson. Cornet realized she accidentally put her sports top on backwards.

She quickly pulled her shirt up then turned away from cameras to place her top on the correct way.

During the roughly 10-second clothing change, she exposed her black sports bra.

Chair umpire, Christian Rask, punished Cornet with a bizarre code violation after the incident which he deemed inappropriate.

The WTA rulebook states that female players are not permitted to change attire while on the court. Male players, however, are permitted to do so.
