Maria Sharapova’s first significant breakthrough in professional tennis was her victory over Serena Williams in the 2004 Wimbledon final. In the years since then, the rivalry has been one-sided; Williams has won their last 18 matches.
In her new memoir, “Unstoppable: My Life So Far,” Sharapova speaks of Williams in a detailed and often antagonistic way rarely used to discuss an active rival. Plenty of tennis players write autobiographies. Few, if any, write so candidly about a rival before they have played their last match.
