Maria Sharapova has the power but hers has custom assist.
New video just out from HEAD Tennis. How powerful is Maria's tennis game? ON in this promo video. Above Sharapova plays with the HEAD Graphene Instinct MP.
Interesting new note in company communications: "HEAD PRO players may play with different racquets from the model shown." Kudos to HEAD for adding this disclaimer. It's about time. Racquet makers have brushed aside the practice for years. Pros at the highest levels play with customized raquets, not the ones we tennis mortals can buy at retail.
