Friday was quarterfinals day at the Coupe Banque Nationale as the remaining eight women in the singles draw were all battling for a place in the final four, while one doubles team were aiming to advance to the showpiece on Sunday afternoon.

Broady, Ostapenko, Beck and Lucic-Baroni advance to semifinals

The day began with a match between Jelena Ostapenko and Paula Kania. Ostapenko has had a great year for an 18-year-old who is playing her first full year on the WTA tour. With a win over Carla Suarez Navarro at Wimbledon, the teenager showed us why she could be a star of the future. The Latvian showed this once again, as she pulled out two gutsy, three-set wins over third seed Mona Barthel and qualifier Jessica Pegula.

Those two matches could have gone either way but Ostapenko was the one who came out on top. Kania, on the other hand, has not had the best year, with a 17-22 win-loss record coming into the Coupe Banque Nationale. The Pole had been playing ITFs for most of her career to eleveate her ranking but she was able to string together two great matches at a WTA tournament to advance to the quarterfinals. With wins over eighth seed An-Sophie Mestach and Sesil Karatantcheva, Kania looked very comfortable at this level, despite her struggles in the past. In this encounter, Ostapenko completely blew Kania off the court, as the 18-year-old won the match 6-0, 6-1 in less than an hour. With this win, the Latvian is now into her maiden semifinal at a WTA event.

Next up, was defending champion and number two seed Mirjana Lucic-Baroni The Croatian seems to play really well in Quebec City, as the indoor and fast conditions really suit her powerful game. Lucic-Baroni continued her winning ways on the campus of the Université Laval, as she easily defeated Canadian Françoise Abanda (by retirement) and Tamira Paszek to reach the final eight. Her opponent would be American Samantha Crawford. Always a talented junior, Crawford has found it hard to transition to the professional tour, but she showed no signs of that as she cruised past Mandy Minella and seventh seed Evgeniya Rodina to get to this stage of the tournament. Judging by the early exchanges, this match was going to be a hard-hitting battle -- literally.

Crawford was perfect on her break point opportunities, as she got an all-important break to win the opening set 6-4. However, in the second set, Lucic-Baroni's experience was beginning to show and she was the one who was able to get the crucial break this time, to win the second set 6-4. In the final set, Crawford looked a little fatigued and Lucic-Baroni was cruising, and as a result, the defending champion won the match 4-6, 6-4, 6-1.

Rounding off the day session was lucky loser Naomi Broady and Anna Tatishvili. Broady, who got into the main draw thanks to a last minute withdrawl from Klara Koukalova. Broady took full advantage of her second chance in Quebec City, defeating both Alla Kudryatseva and Alexa Glatch to advance to the quarter finals. Now aiming to book a place in the semifinals, Broady had to get past Anna Tatishvili. Tatishvili was supposed to play number one seed Madison Keys in the opening round but Keys withdrew, giving the American a big opportunity to go deep in this tournament.

Tatishvili has had no easy road to get to this stage of the competition though, as she defeated lucky loser Nadiia Kichenok and pulled out a gutsy three-set win against her compatriot Louisa Chirico. In the quarter finals, it was a case of who had enough in the tank. Tatishvili capitalized on her two break point opportunities in the opening set to win it 6-3, before Broady got a crucial break that would be enough to win the second 7-5. In the end, the Brit's powerful game and big serve was too much for the American to handle, as Broady won 3-6, 7-5, 6-3 to advance to her first WTA semi final of 2015.

The night session began with a match between fifth seed Annika Beck and fourth seed Lucie Hradecka. Beck has had an up-and-down year where she lost in the first round or failed to qualify for a tournament a total of 16 times. But if you put that aside, you will see that Beck plays really well indoors. After winning her maiden WTA title in Luxembourg last year, the

German seems to feel most comfortable with a roof over her head when she plays, and the conditions suit her game. Beck breezed by Canadian Sharon Fichman and got the better of Andrea Hlavackova to get to the final eight in Quebec City. Her opponent, Lucie Hradecka, has had a pretty good year, with wins over Ana Ivanovic and Sara Errani, as well as making her seventh WTA final in Prague. Like Beck, Hradecka plays really well indoors, and she showed why against Donna Vekic and Amandine Hesse. In this quarter final, Beck defeated Hradecka handily by a score line of 6-0, 6-3 as she outclassed her opponent from start to finish.

After all four quarter finals concluded, it was determined that Naomi Broady would play Jelena Ostapenko and Annika Beck would play Mirjana Lucic-Baroni. The winner of those two respective matches will meet on Sunday afternoon. All four players are looking for their first WTA title of 2015.

Krejcikova and Mestach book place in showpiece

Meanwhile on the doubles side, Barbora Krejcikova and An-Sophie Mestach played Annika Beck - who had just finished her singles match less than an hour prior - and Evgeniya Rodina. It was clear from the get-go that Krejcikova and Mestach were the better team, despite never playing a match together before this week. In the end, it was the Czech-Belgian duo that reigned supreme with a 6-3, 6-1 win in the semi finals.

Krejcikova and Mestach will play Naomi Broady and Amandine Hesse or third seeds Maria Irigoyen and Paula Kania in the doubles final, this Sunday.
