Canada's Milos Raonic rolled into the semifinals of the Western & Southern Open Friday with a 6-1, 6-0 dismantling of Italy's Fabio Fognini.

It took only 57 minutes for the fifth-seeded Raonic to dispatch his 15th-seeded opponent. Raonic broke Fognini six times and saved all seven break points against his own serve. The Canadian had seven aces and took the victory when Fognini hit two straight double-faults.

"I had to do a lot of things well today, he's very unpredictable," Raonic said. "I tried top take advantage of his little slumps.

Raonic, from the Toronto area, will face Roger Federer, who defeated Andy Murray 6-3, 7-5 on Friday night. Saturday's semifinal is scheduled for 9 p.m. ET.

The Swiss star and No. 2 seed has won the Masters event an unprecedented five times already.

Raonic lost in straight sets to Federer in the Wimbledon semis last month.

This will be the Canadian's fourth semifinal of the season after Rome, Wimbledon and Washington, where he won his sixth career title.

Federer was on the offensive from the first point as he evened their career series at 11 wins apiece and showed he's going to be tough to beat.

Murray had saved all five break points this week, holding service in 26 games. He fought off that many break points in his first two games against Federer, who kept the pressure on, broke him to go up 3-2 and served it out.

Murray appeared to gain a toehold when he broke Federer twice for a 4-1 lead in the second set, but Federer broke him twice to even it and then one more time to finish it off.

Elsewhere, sixth-seeded David Ferrer knocked off Robredo 6-4, 3-6, 6-3, reaching the semifinals for the first time in 11 appearances in Cincinnati.

Pospisil into doubles semis

Wimbledon champions Vasek Pospisil of Vancouver and American Jack Sock reached the doubles semifinals with a 6-2, 5-7, 10-7 win over Alexander Peya of Austria and Bruno Soares of Brazil, who won the doubles title last week at the Rogers Cup in Toronto.

Pospisil and Sock have now won a record 13 straight matches since first playing together at Wimbledon. They topped the previous mark of 12 set by Paul Annacone and Christo van Rensburg in 1984-'85.

Wawrinka knocked out

Julien Benneteau upset Australian Open champ Stan Wawrinka in the men's quarters, with the unseeded Frenchman roaring back to win 1-6, 6-1, 6-2.

The third-seeded Wawrinka needed only 20 minutes to win the first set before unraveling with a string of unforced errors. He had 18 in the third set alone, while Benneteau had just five.

"It was a strange match, for sure," Wawrinka said. "Even when I was winning the first set, 6-1, I wasn't playing well. I wasn't moving well."

Benneteau has beaten Wawrinka in three consecutive matches. He reached the semifinals in Cincinnati for the first time.

Serena makes short work of Jankovic

In the women's draw, top-seeded Serena Williams needed just 58 minutes to beat Jelena Jankovic 6-1, 6-3.

Williams has never won the tournament in five previous appearances.

The American had seven aces to none for the eighth-seeded Jankovic, who won the tournament in 2009. Williams also owned a 22-5 advantage in winners.

"Obviously, it was a bad day," Jankovic said. "I felt slow. For some reason, I was late on shots. I didn't do anything well. She didn't have to do a lot. She played her game, and I didn't do anything to disrupt that."

Williams will face Caroline Wozniacki, who beat Agnieszka Radwanska 6-4, 7-6 (5) to reach the semifinals in Cincinnati for the first time in seven tries.
