US Open chiefs said they were wrong to sanction French player Alize Cornet for removing her shirt on court, an incident which saw the tournament accused of sexism and double standards. Cornet slipped off her shirt, revealing a black sports bra, after realising she had put it on back-to-front while off court during a 10 minute heat break before the third set of her first round defeat against Sweden's Johanna Larsson. However, there was a storm of criticism for umpire Christian Rask's decision to issue a code violation to year-old Cornet while male players were free to change shirts on court to combat Tuesday's 38C heat. This is not considered a code violation," said organisers in a statement issued Wednesday.
