(CNN) Aslan Karatsev's historic run continued at the Australian Open on Tuesday as the Russian became the first man in the Open Era to reach the semifinals on his grand slam debut. 114 stunned a clearly injured Grigor Dimitrov 2-6, 6-4, 6-1, 6-2 at Rod Laver Arena. The Bulgarian took a medical timeout in the third set because of an apparent back injury, but his condition didn't seem to improve afterwards. Karatsev, who had previously attempted to qualify for nine grand slam championships, is only the fifth qualifier to reach the semifinals of a grand slam in the Open Era with a victory which took two hours and 32 minutes. Of course, it's my first time playing [a Grand Slam] main draw, first time [in the] semis," Karatsev said in his on-court interview.
