Fantastic insights by Spadea. He explains clearly what hitting through the ball means and how important it is - and uses Fed as an example. He knows exactly what he is talking about - the way the modern forehand is hit. "Firm through". 'Firm through does not mean firm across, it means firm through." "Coming across early means leaving the track and derailing the train."
LOL what a blow to the "coaches" here who have been advocating "yanking" and "pulling" and their followers trying to twist everything to see if it fits that description. Wake up guys, listen to modern players who have actually played at a high level, not club-level playing coaches who just want to play with words. Listen to how Spadea admires all the top players - no false dichotomies and strawmen here.
