Maria Sharapova has become synonymous with excellence and resilience. Despite a shoulder injury that limited her performance in 2007, the Russian-born tennis player continued to make it into Top 5 rankings in world championships and won five Grand Slams (via WTA Tour). After 28 years in tennis, the Olympic silver medalist retired in early 2020 with a heartfelt essay for Vanity Fair. "I'm new to this, so please forgive me," she wrote. "Tennis — I'm saying goodbye."
