In 1979, he made his first appearance for the Soviet Davis Cup team.
Zverev was a bronze medalist in the men's singles event at the 1983 Summer Universiade and won a singles gold medal at the Friendship Games, which were held in 1984. He did better than two years earlier at the 1985 Summer Universiade, winning both the singles gold medal and the doubles gold medal, partnering Sergi Leonyuk, with whom he was also a gold medalist in the 1986 Goodwill Games.
He appeared in three Grand Slam tournaments during his career. In the 1985 Australian Open he qualified for the main draw and was beaten in the opening round by Tim Wilkison. Again playing as a qualifier, Zverev met Tim Mayotte in the first round of the 1986 Wimbledon Championships and was defeated in straight sets. As a mixed doubles player he took part in the 1986 French Open, with Svetlana Cherneva.
Zverev played mostly on the Challenger circuit, where he had victories over two top 50 players, Andrei Chesnokov and Jan Gunnarsson. He did however make the second round of the 1985 Geneva Open, a Grand Prix tournament.
He played his final Davis Cup tie in 1987 and retired having taken part in 36 rubbers, from which he won 18. One of those was a doubles win over the Czechoslovak pairing of Libor Pimek and Tomáš Šmíd, the latter ranked number one in the world for doubles at the time.
