Oh I say, now that is a winner right out of this world! Well, you won't see a better shot than this, hit after this marvelous lob from Jimmy Connors, who catches McEnroe moving forward – a classic moment for the lob – and McEnroe hesitates, realises he can't really hit the overhead cleanly – it's beaten him – chases it back and unleashes... a backhand such as you dream about.
