Melbourne, Australia (SportsNetwork.com) - The women will also have a new champion at the Australian Open. After three-time reigning mens titlist Novak Djokovic lost here on Tuesday, fifth-seeded Pole Agnieszka Radwanska took down two-time defending champion Victoria Azarenka 6-1, 5-7, 6-0 on Wednesday to set up a semifinal match with Dominika Cibulkova of Slovakia. "Im so happy and pleased, especially that I beat one of the best players in the world," Radwanska said. "Was not easy draw, not easy quarterfinal. Im very happy that I made my first semifinal here." The second-seeded Azarenkas 18-match winning streak in Melbourne came to a halt on Day 10. She was trying to become the first woman to win the singles title here in three consecutive years, or since Martina Hingis turned the trick from 1997-99. Radwanska, who ended a streak of three consecutive quarterfinal defeats at the Aussie Open, committed just 15 unforced errors compared to 47 for Azarenka. "She was aggressive. She was making everything. She was guessing right. I was just playing a little bit too predictive, you know," Azarenka said. Azarenka had been a dominant 12-3 lifetime against her fellow 24-year-old Radwanska, including a come-from-behind Aussie quarterfinal victory two years ago. Meanwhile, the 20th-seeded Cibulkova cruised past 11th-seeded Romanian Simona Halep 6-3, 6-0 in a match that lasted just 60 minutes to secure her spot in the final four. The 24-year-old Cibulkova, who stunned No. 3 seed Maria Sharapova in the fourth round on Monday, is the first woman from Slovakia to reach the Aussie Open semis since Daniela Hantuchova in 2008. The diminutive Cibulkova improved to 2-3 in quarterfinal matches at Grand Slams, with her other win coming at the 2009 French Open. "That time I was 19 years old. I was pretty young. I would say also a different player. You know, I am much more experienced," Cibulkova said. Halep, who upended former world No. 1 Jelena Jankovic in the fourth round, appeared overwhelmed in her Grand Slam quarterfinal debut. "No, just I couldnt play today. I had emotions, big emotions, and I couldnt manage this," she said. "Before the match I was very nervous and I didnt feel the ball at all. I couldnt move my body and I couldnt play." Fourth-seeded Chinese star Li Na and 30th-seeded blossoming 19-year- old Canadian Eugenie Bouchard will meet in the other semifinal on Thursday. The former French Open champion Li is a two-time runner-up at Melbourne Park, including last year against Azarenka. Custom Colorado Avalanche Jerseys .

CHICAGO -- Jake Arrieta took the ball for the Chicago Cubs and picked up right where he left off. He threw his fastball where he wanted it to go. His breaking stuff had good late movement. The Cincinnati Reds finally had to put him on base to get him out of the game. Arrieta retired his first 18 batters and struck out nine in seven impressive innings, leading Chicago to a 7-3 victory over Cincinnati on Tuesday night. "He was commanding his pitches," Cubs manager Rick Renteria said. "His pitches had life." Arrieta (4-1) struck out eight during his perfect start, including the side in the sixth. He had a leadoff walk in the bottom half and came around to score when Homer Bailey (7-4) hit Starlin Castro with the bases loaded. That little trip around the bases proved costly. Rookie Billy Hamilton started the seventh with a single up the middle for Cincinnatis first baserunner. "I was pretty gassed there, unfortunately," Arrieta said. "Pretty humid night. Long inning there in the sixth. Running the bases, which really isnt all that tough in itself, but you couple that with being on the mound and having that long layoff, it adds a little bit to it." Arrieta allowed two runs and three hits while improving to 3-0 with a 1.14 ERA in five June starts. It was his first win of the season at Wrigley Field, where he has yielded three runs in 23 innings over four starts. "Really its just kind of going through the process that I feel like gives me the best chance to have success," he said, "and going through it day by day and sticking with it." Anthony Rizzo belted a solo homer for the second straight night for the Cubs, who snapped a three-game losing streak. Welington Castillo drove in two runs, including a sacrifice fly in Chicagos three-run eighth. Devin Mesoraco homered for the fifth straight game for Cincinnati, matching a franchise record. Mesoracos 14th homer came with one out in the ninth against Neil Ramirez. "It was late in the game. All the other homers were to help the team wiin, and important, big homers," he said.dddddddddddd "They actually meant a lot. That one didnt really help us come back, so it doesnt mean as much." Mesoraco also had an RBI single in the seventh and scored on Jay Bruces double before Arrieta struck out Ryan Ludwick to complete his masterful night against one of the majors hottest lineups. Cincinnati had won three straight and nine of 12, averaging 6.7 runs and 10.2 hits per game in that stretch. The Cubs used four relievers to get through the eighth, and Ramirez finished Chicagos 12th win in 42 games against Cincinnati over the last three seasons. The Reds had runners at first and second in the eighth when third baseman Mike Olt made a nice diving stop on Todd Fraziers grounder for the final out of the inning. The start of the game was delayed 53 minutes by rain, but the pitchers adjusted quite nicely to the late start. Bailey retired his first 11 batters, striking out five. But Rizzo drove the first pitch he saw in the fourth inning into the basket in right-centre for the first of his three hits and his 17th homer this season. Castillo added a run-scoring double in the fifth, and the Cubs chased Bailey while scoring two more in the sixth. Nate Schierholtz had a sacrifice fly for the first of his two RBIs. Bailey allowed four hits, struck out six and walked two in his first loss at Wrigley since he pitched 5 1-3 innings in his first career appearance at the cozy neighbourhood ballpark on Sept. 13, 2009. The right-hander began the day with a 5-1 record and a 2.56 ERA in seven road starts against the Cubs. "Just bad pitch execution in the last inning or two," Bailey said. "That was probably the only thing I saw." NOTES: Hamilton extended his career-best hitting streak to 12 games. ... Cubs OF Emilio Bonifacio (rib injury) is working out, but has yet to resume baseball activities. "Hes improving," Renteria said. ... Reds RHP Mat Latos (0-0, 3.86 ERA) and Cubs RHP Edwin Jackson (5-7, 5.12 ERA) pitch in the series finale Wednesday. ' ' '
