(Reuters) - Canadian Eugenie Bouchard has lashed out at the WTA for giving Maria Sharapova the chance to compete in tournaments after serving a 15-month doping ban and said the Russian is a "cheater" who should never be allowed to play again.

Sharapova beat Italian Roberta Vinci in the first round of the Stuttgart Grand Prix on Wednesday after receiving a controversial wild card for the tournament, having lost all her ranking points in the wake of her suspension.
