I noticed when playing online matches, a lot of the times my opponent would be on one end of the baseline, while I would hit to the other end. But somehow, they would suddenly burst into a super fast sprint (it's like the flash sprint -_-;;) and retrieve the ball. This happens especially when playing Nadal.
Is there a button to press to super fast sprint to the ball so quickly? I tried pressing R1 (I'm on PS3), but the speed is not as fast though. Appreciate any help on this, thanks.
