first round of the Davis Cup Europe/Africa zone in 2009. Dimitrov was victorious in both his singles rubbers which led to a narrow 3–2 victory over Hungary. He would then take a few breaks from Davis Cup which would result in Bulgaria being relegated back to the lowest division of Davis Cup. Dimitrov would return to Davis Cup competition in 2012 as a top 100 player. The Bulgarians breezed through the round robin tournament held in their home city of Sofia and would once again be promoted to the second division of the Europe/Africa zone. Dimitrov and the Bulgarian Davis Cup team have been unable to advance past the first round since being promoted but have been victorious in their two relegation ties. Olympics Dimitrov represented Bulgaria at his maiden Olympics in 2012 London. He competed in the singles competition and advanced past the first round with a straight sets victory over Poland's Łukasz Kubot. He was then beaten by France's 12th seed Gilles Simon. Dimitrov made his second Olympic appearance in 2016 Rio where he was beaten in the first round of the singles competition by Croatian Marin Čilić.

As his talent became more apparent he started to receive coaching from abroad, most notably from Spaniard Pato Alvarez, who has also coached Britain's Andy Murray.
