Rafael Nadal recovered from a slow start, overcoming Marin Cilic 2-6, 6-4, 6-4 to keep his chase for a long-sought ATP Masters title on hardcourt alive on Friday.
The world No 1 reached the semifinals in Toronto and will next face Russian Karen Khachanov, who beat Robin Haase 6-3, 6-1 earlier in the day.
“It was a very important match for me,” Nadal said. “Being in semifinals is great news at the start of the hard court season.
“And winning three good matches in the first Master 1000, it’s so important for me.
“He played unstoppable in the first set. I resisted, I played with the right tactic. I tried to find my solutions – but it was so difficult.”
Stefanos Tsitsipas saved two match points to beat defending champion Alexander Zverev in their quarterfinal contest 3-6, 7-6 (13/11), 6-4.
The Greek teenager, who turns 20 on Sunday’s final day, defeated his third straight top 10 opponent at the tournament after knocking out Dominic Thiem in the second round and 13-time major winner Novak Djokovic in the third.
Tsitsipas is the youngest player to post three top 10 wins at a single tournament since the 19-year-old Nadal at Monte Carlo in 2006.
Tsitsipas will next face Wimbledon runner-up Kevin Anderson, who swept past Grigor Dimitrov 6-2, 6-2.
“I’m confused now, is this real?” 27th-ranked Tsitsipas said after completing his prestige hat-trick of upsets.
