Maria Sharapova set up a mouth-watering second-round clash with Eugenie Bouchard at the Madrid Open after battling back from a set down to beat Mirjana Lucic-Baroni 4-6, 6-4, 6-0 on Sunday.

Bouchard called the Russian "a cheater" last week and suggested she should have been banned for life -- rather than 15 months -- after testing positive for meldonium at the 2015 Australian Open.

And the Canadian said she would "have a bit more motivation" against her former idol Sharapova after registering a first win on the WTA Tour since January against Alize Cornet on Sunday to set up the grudge match.

After reaching the semi-finals on her return from her doping ban last week in Stuttgart, Sharapova showed impressive levels of fitness to dig deep after a tough couple of opening sets against world number 20 Lucic-Baroni.
