Fourth seed Simon battled past Taro Daniel, saving 12 of 15 break points, in a 6-4, 7-5 victory over two hours and 34 minutes on Friday for a place in the semi-finals against Andujar, who advanced without playing when his Czech opponent Jiri Vesely withdrew due to a right toe injury.
Benoit Paire booked his place in the semi-finals for the second time in three years by knocking out #NextGenATP Spaniard Jaume Munar 6-1, 6-3 in 59 minutes. Munar had overcome World No. 3 Alexander Zverev in the second round on Thursday.
“I played aggressively today and was able to bother him,” said Paire. “I made the right choices and I’m really happy with my match today.”
