but as I hung up I realized I was furious. I grabbed my racket, ran down to the court and began hitting balls harder than I ever had before. Amazingly, most of them went in. I didn’t let up when the match began, nor did I relent my all-out attack until it was over. Even on crucial points I would go for winners and make them. I was playing with an uncharacteristic determination even when ahead; in fact I was playing out of my mind.
