Monte-Carlo Masters
In 2007, Kohlschreiber achieved his greatest result at an ATP Masters Series event during the Monte-Carlo Masters, when he reached the quarterfinals after going through qualifying, defeating world No. 12 David Nalbandian in the second round. He won his first career title in Munich defeating Mikhail Youzhny, thereby becoming the first German player to win the event since Michael Stich in 1994.
