Evolve Your Game. Yonex has done the impossible and improved on their bestselling Astrox 88D Pro. Built for players that like to play in the back of the court to send powerful smashes and clears, the 88D Pro pairs perfectly with the 88S Pro. With the 88D Pro you can push back opposing players and hit winning shots or have your partner finish them off at the net with the 88S Pro. The 88D Pro was built to perform under the fast-paced play of doubles and is also suitable for singles players looking for more power.
