MONTREAL: Top-seeded defending champion Rafael Nadal of Spain advanced to the Rogers Cup final Saturday night when Gael Monfils of France withdrew before their semifinal.

Nadal will face eighth-seeded Daniil Medvedev, a 6-1, 7-6 (6) winner over sixth-seeded Karen Khachanov in the all-Russian first semifinal.

鈥淚t鈥檚 extra special,鈥� Medvedev said about facing Nadal for the first time. 鈥淚 played Novak (Djokovic) and Roger (Federer) a few times. It鈥檚 different ... there is some extra pressure.鈥�

Nadal won last year in Toronto for his fourth title in the event. He has 82 singles victories, winning the French Open in June for his second title of the year.

Monfils, seeded 16th, outlasted 10th-seeded Roberto Bautista Agut of Spain 6-4, 3-6, 7-6 (2) in a match suspended Friday night because of lightning. Monfils finally finished off Agut after a rain delay Saturday, but battled a sore left ankle that forced him to pull out of the semifinal.

鈥淚 love these matches, night session, Rafa,鈥� Monfils said. 鈥淚 play tennis for that 鈥� for the big moments, big shows. It was safest decision not to play.鈥�

Monfils consulted with his coach about the decision to withdraw.

鈥淗e said, 鈥榊ou can鈥檛 take the risk,鈥欌€� Monfil said. 鈥淚 had retired in Wimbledon. I came back. I played this week. I had played a huge match. It was risky to play another match because I could risk hurting myself for real.鈥�

In Toronto, teenager Bianca Andreescu advanced to the Rogers Cup title match with a 6-4, 7-6 (5) victory over Sofia Kenin on Saturday, becoming the first Canadian in 50 years to make the women鈥檚 final.

The 19-year-old Andreescu, from nearby Mississauga, will face Serena Williams on Sunday.

鈥淭he crowd will obviously be for her, but it鈥檚 really not about that,鈥� Williams said. 鈥淚t鈥檚 just about going out there and playing your great tennis. Luckily, I鈥檝e had some tough crowds in my career, so hopefully I will be used to it.鈥�

Canadians Faye Urban and Vicki Berner played in the 1969 final, with Urban winning the tournament that was played on clay and called the Canadian Open.

鈥淔or sure there鈥檚 some pressure, but I have nothing to lose, really,鈥� Andreescu said. 鈥淲e鈥檒l see how it goes. I鈥檓 just going to try and stay in the present moment.鈥�

Williams beat Czech qualifier Marie Bouzkova 1-6, 6-3, 6-3 in the second semifinal.

The 37-year-old Williams is ranked 10th and seeded eighth in her first event since losing the Wimbledon final. She won in 2001, 2011 and 2013 鈥� all in Toronto 鈥� and has a tournament-record 34 victories in 38 matches. The American won the last of her 72 singles titles in the 2017 Australian Open.

Andreescu is returning from a right shoulder injury that sidelined her since the French Open in May. She won in Indian Wells in March for her first WTA Tour title.
