Anett Kontaveit spoiled Maria Sharapova’s return, rallying to beat the five-time Grand Slam champion 4-6, 6-3, 6-4 in the opening round of the Rogers Cup on Monday.
Sharapova, competing for the first time since retiring from her first-round match at Wimbledon, appeared to be on course for her fourth match win since January when she went up a set and an early break against the 16th seed from Estonia.

German 12th seed Angelique Kerber was unable to make it to the second round, losing 0-6, 6-2, 6-4 to Russia’s Daria Kasatkina.
