Grigor Dimitrov earned his 400th tour-level win on Saturday at the Chengdu Open, where he moved past Peruvian Juan Pablo Varillas 6-3, 6-4 to reach the quarter-finals at the ATP 250.
The Bulgarian, who is making his third appearance at the Chinese hard-court event, struck the ball cleanly in his first Lexus ATP Head2Head meeting against Varillas. He also recovered from squandering a break advantage in the second set to advance after one hour and 26 minutes.
The 32-year-old captured his first win at an ATP Tour event in Rotterdam in 2009, defeating Tomas Berdych in three sets. Dimitrov has since lifted eight tour-level titles, rising to a career-high No. 3 in the Pepperstone ATP Rankings.
Dimitrov will next face Christopher O’Connell as he continues his quest for his first title of the season. Earlier this year, the World No. 20 reached the final in Geneva.
Frenchman Arthur Rinderknech also advanced, defeating Marcos Giron 7-6(2), 6-4 to reach his second tour-level quarter-final of the season. Rinderknech will next meet Lorenzo Musetti or Philip Sekulic.
