Serena Williams is primarily a baseline player. Serena Williams' game is built around taking immediate control of rallies with a powerful and consistent serve (considered by some to be the best in the women's game), return of serve, and forceful groundstrokes from both her forehand and backhand swings. Serena Williams' serve is technically very sound and has been hit as hard as 129 mph (206.5 km/h), the second-fastest (after her sister Venus) all-time among female players.
