Maria Sharapova (unranked to 262): The five-time Grand Slam champion returns to the WTA Rankings this week after reaching the semifinals in Stuttgart. The last time Sharapova appeared in the WTA Rankings was the week of October 17, 2016 (at No.91).
It's been nearly eight years since the Russian had an official WTA Ranking outside the Top 100, having been ranked No.102 for the weeks of May 25, 2009 during the 2009 French Open. The event was just her second after returning from a right shoulder injury, which forced her to miss nine months of action.
