Rădulescu began playing tennis at the age of seven. He came to Germany at the age of 14 and took German citizenship in 1993. He played for the Rochusclub Düsseldorf and trained with Klaus Hofsäss . In the 1990s he was one of the best German tennis players and was known for his strong serve, which was favored by his body length of 1.88 m. As a junior player he reached the junior final of the French Open in doubles in 1993 together with Yevgeny Kafelnikow and was able to secure the German championship title in doubles in the same year.
In 1996 he had his greatest international success when he surprisingly made it into the quarterfinals of Wimbledon in his first Grand Slam tournament . He defeated Arnaud Boetsch , Stefano Pescosolido and David Wheaton in five sets, before failing in five sets at the later finalist MaliVai Washington . In the fifth set, Rădulescu overruled a referee's decision to his disadvantage when the score was 4: 4; he lost the set 4: 6 and with it the game. For his behavior he received the fair play plaque from the German Olympic Society . His coach at the time was Ulf Fischer.
His highest ranking in the world rankings was 51st in March 1997. That year he also made the only final appearance at an ATP tournament in Chennai , where he lost to the Swede Mikael Tillström . In the same year he reached the third round of the US Open , where he lost to Pete Sampras . He also had his best double result in 1997, when he failed together with Nicolas Kiefer in Singapore only in the semi-finals.
Rădulescu lives and works today as a tennis trainer in Munich.
