Andrey debuted in 2016 at the Qatar Open, losing in the quarterfinals to Rafael Nadal in three tight sets. At the 2016 Australian Open, he got his best ever result in a grand slam, beating Dudi Sela to make it to the fourth round. In the following tournaments he successfully got beyond the first rounds. Reaching the second round of the Miami Open, Kuznetsov became Russia's new number one male tennis player, replacing Teymuraz Gabashvili, who lost in Miami in the first round. Kuznetsov in the second round confidently defeated 4th-seeded Stan Wawrinka, the second time he won against a top-10 player. He then proceeded to beat Adrian Mannarino in the third round 2–6, 7–5, 6–0. In the fourth round he lost to Nick Kyrgios 6–7, 3–6.

At the 2015 Australian Open, he got into the second round, but lost to Novak Djokovic.

At Wimbledon in 2014, Kuznetsov recorded his first win over a player ranked inside the world's top ten by defeating seventh seed David Ferrer in five sets.

As a junior Kuznetsov posted an 80–24 win/loss record in singles, reaching a combined ranking of No. 3 in the world in July 2009.

Patrick Mouratoglou in 2011 noted his flat shots, nice serve and volley play and a great forehand, but also felt his shot placement and movement should be improved.

He made his first main draw Grand Slam appearance at the 2010 Wimbledon Championships where he lost in five sets to seeded Romanian Victor Hănescu. He defeated the 11th seed of the 2013 Australian Open, Juan Mónaco in straight sets in the first round to reach the second round of a grand slam for the first time.

Kuznetsov played his first ITF junior tournament at the 2006 Black Gold of Udmurtia, but received a walkover in the qualifying round. His first notable achievement was at the Governor Cup in St. Petersburg, reaching the semi-finals there. He reached his first final at the NBU Cup in Uzbekistan. Most of the tournaments were on a clay court, but in 2007 he played on carpet and hard. In this season he reached three finals in singles, winning once, and three doubles finals in doubles, winning twice. His best season was in 2008, when he won three singles titles and played well in doubles. Andrey's last junior tournament became the 2009 Wimbledon, winning his first Grand Slam title. For the first time in 43 years a Russian won the Wimbledon since Soviet Vladimir Korotkov achieved that feat in 1965 and 1966.

Andrey Kuznestov started playing tennis at age six, coached by his father Alexander. In 2001, his family moved to Balashikha, attending the sports club there. His father resumed coaching Andrey and his elder brother Alexey.
