Grigor Dimitrov completed the semifinal lineup at the 2021
San Diego Open, overcoming
Aslan Karatsev in a tricky encounter on Friday night.
The former World No.3 stifled a Karatsev comeback, prevailing 6-1 1-6 6-2 in a match that saw many shifts in momentum. Dimitrov breezed through the first set after just half an hour, employing his speed and athleticism to confound his opponent.
However, there was a reverse of fortunes in the second set as Karatsev seemed to have all the momentum, with his Bulgarian opponent looking out of sorts. Dimitrov was unable to develop a rhythm, hitting six double faults in the process. With the second set out of reach, it came down to a decider.
The final set saw Dimitrov grab an early break to lead 3-1, only to be broken immediately by the crafty Russian. This was short-lived, as Karatsev was unable to capitalize on his momentum, losing serve almost immediately before being broken a second time and ultimately handing the World No.29 the match.
