Serena Williams’s first serve continues to be the most dominant shot in women’s tennis. Her 7-5, 6-3 defeat of Angelique Kerber in the 2016 Wimbledon championship is the most recent example of how well she serves and how her first serve can set the tone for her victories. She lost serve six times in her first four rounds and then turned up the power as she neared her 22nd Grand Slam singles title. In her last three matches she faced only one break point and did not lose serve. She won 97 of 107 first serve points (91%) and hit 35 aces in those three matches. Serena hit 69% of her first serves in play over those three matches which is pretty amazing considering how aggressively she was serving.
