Rafael Nadal vs Alexander Zverev: 3 reasons why Nadal won the Davis Cup rubber comfortably

#2 Rafael Nadal's forehand was on fire:

Rafael Nadal's forehand is one of the best shots in tennis history. It was on full display against Zverev and he hardly put a foot wrong. From the beginning of the first set, Nadal was able to move Zverev around the court with his powerful forehand. On numerous occasions, he opened up the court with his forehand and punished Zverev.

When Nadal's forehand clicks it just becomes impossible for the opponent to attack. While Zverev can be criticized for offering some short balls to Nadal's forehand, his forehand was just too good and helped him win the crucial encounter to help Spain tie things up.
