Maria Sharapova won't buy into 'cheat' slanging match with Eugenie Bouchard

Sharapova returned to tennis Wednesday in the opening round of the Porsche Tennis Grand Prix in Stuttgart, Germany, and she was victorious, despite being away from the sport for more than a year.

Yet Sharapova continued her impressive form, simply dismantling her Estonian opponent 6-3 6-4.

"I don't think that's right and (Sharapova is) definitely not someone I can say I look up to any more".

Eugenie Bouchard has taken a swipe at Maria Sharapova following the Russian's return to the court after a doping ban. It's a fact that she was caught by anti-doping, but she wasn't the first one.

Having also been given wild cards to play at the Madrid and Rome tournaments, Sharapova must wait until May 16 to learnt if she will get a wild card for the French Open.

The draw has been kind to Sharapova - the frailties of the sport's leading lights mean she has not yet faced a top-30 player - but she is playing exceptionally well after 15 months free of competition.

Sharapova says she would "play in the juniors if I have to" in order to compete at the French Open and Wimbledon, but has no interest in building bridges with her rivals.

Sharapova, a former world No. 1 and five-time Grand Slam champion, wasn't allowed at the venue until the morning of the match.

Ahead of the Women's Stuttgart Open, the Canadian star didn't hold back against her former idol.

The Russian, who tested positive for meldonium at last year's Australian Open, will next face either Kristina Mladenovic or Carla Suarez Navarro.

Sharapova broke twice in the first set and once in the second to breeze past Kontaveit in just under an hour-and-a-half.

Sharapova has already been slammed by several other players who are unhappy that the five-time Grand Slam champion has been given wild-card entries to some tournaments.

Sharapova has maintained she did not cheat intentionally, instead saying she missed the memo that said meldonium was a banned substance. "But I love the game and I love great rivalries". I didn't know when I would be back.

But the seven doubles were outweighed by nine aces, the last of them on her first match point.

Sharapova has played vs. Vinci on two occasions in the past and has emerged victorious for both matches.
