Tennis - Former World No. 2 Tommy Haas has said that he is certain that his young compatriot Alexander Zverev would win a Grand Slam singles title at some point in his career. Zverev has triumphed at the Masters 1000 level and also won the season-ending ATP Tour Finals in London last year but the 21-year-old has progressed beyond the fourth round of a Grand Slam event only once in his career - at the 2018 French Open.
Speaking to Tennis Bulgaria, Haas commented, "His family has a great experience in tennis, and his brother Misha is also an excellent tennis player, and Alexander has already proven he has great qualities and potential, and he can achieve much more.
You see he's in a young age, but he's already managed to won several very big tournaments. He is tall and he can make powerful kicks from the bottom of the court, and he's very confident in himself, which is a huge plus for this level, and I'm sure he will win a Grand Slam trophy."
Haas was speaking after Zverev was beaten in the final of the Acapulco Open in Mexico by Australian Nick Kyrgios. Zverev did combine with brother Mischa to win the doubles title in Mexico. The German is currently ranked No.
3 in the world behind behiind Serbian Novak Djokovic and Spaniard Rafael Nadal. Zverev started 2019 by reaching the fourth round of the Australian Open for the first time in his career. His best performance at Wimbledon has been reaching the fourth round in 2017 and the third round at the US Open in 2018.
