One year ago, Zverev made his debut at The O2, falling short of reaching the semi-finals. But the 10-time ATP World Tour champion showed his growth, beating six-time champion Roger Federer in straight sets on Saturday and now Djokovic for the victory. Entering the match, all signs were pointing to Djokovic tying Federer’s record of six triumphs at the season finale. The Serbian had won 35 of his previous 37 matches entering the final, and all 36 of his service games this week at The O2. Four days ago, he had beaten Zverev with the loss of just five games in round-robin play. But from the first point of the match, Zverev showed no fear, standing on the baseline and trading blows with Djokovic, who for the first time all tournament appeared to be scrambling, and not the in-control defensive wall that had diffused attacks from the very best players in the world.
