Denis Gremelmayr, a 27-year-old German tennis player was born on August 16, 1981 in Heidelberg, Germany. He started playing tennis at the age of five while accompanying his parents during their tennis matches. During his amateur years he was one of the top 10 in Germany until he reached the age of 16 and reached the top spot before turning pro, although he did not play in any international junior tournaments.
Gremelmayr turned pro in 2000 and reached the 97th spot in the rankings on August 2006. Before that he had reached the 1st round in Wimbledon and the 3rd round in the US Open in 1999. He spent 2007 in the top 200 and by the time the year was over, he had progressed to a spot at 119.
A few years later he had to make a few changes in his training schedule for his duties in the German Army, which required four to five days a month for eight months for Army training. This reduced his playing schedule to two tournaments a month, a far cry from the usual 10 tournaments a month which other German players were used to.
He reached the second round of the 2008 Australian Open before losing to American tennis player Vince Spadea after five sets. He also reached the semifinals in the Estoril Open but was defeated by top seeded Roger Federer after 3 sets. Known mostly for his defensive games, he can also play an aggressive game, especially because he can hit hard with either hand.
He currently has a record of 20-24 in singles and a 2-6 in doubles. He reached a career high ranking of 59 in May 5, 2008 in singles, while his highest ranking in doubles remains at 284, a spot he gained on April 14, 2008.
