STUTTGART, Germany -- Two-time defending champion Maria Sharapova needed eight match points to put away top-seeded Agnieszka Radwanska 6-4, 6-3 Friday for a place in the Porsche Grand Prix semifinals. Fabio Coentrao Shirt . Sharapova has won 11 consecutive matches on Stuttgarts indoor clay. Her semifinal opponent will be eighth-seeded Sara Errani, who was leading 6-3, 6-7 (6), 3-0 when Carla Suarez Navarro retired with a hand injury. "This was a big victory for me, the biggest since my injury," said Sharapova, who returned late last year after missing more than four months following shoulder surgery. Ana Ivanovic outlasted 2009 Stuttgart champion Svetlana Kuznetsova 6-3, 2-6, 6-4 in a battle between two former French Open winners. Ivanovic is seeking her third title of the year and is the only player remaining in the tournament to have won an event this year. Radwanska played her best tennis in the penultimate game, when she fought off six match points and finally broke Sharapovas serve. Under pressure from Radwanska, Sharapova made two straight backhand errors as she dropped her serve. But Radwanska could not keep the momentum and Sharapovas forehand winner down the line gave her two more match points. Sharapova wasted the first with a wild forehand that was both long and wide, but then nailed a forehand winner to the corner to end the match. Sharapova is aiming for her first title of the year and the 30th of her career. Ranked No. 9, she would have fallen out of the top 10 with a loss Friday. "Ive been on the tour for so long I wasnt really thinking about it," she said. Suarez Navarro received treatment after winning the second set and quit three games later.

Mariota threw for two touchdowns and ran for another and No. 2 Oregon defeated California 55-16 on Saturday night in a drenched Pac-12 opener for both teams. "Ive been playing in the rain since I was a little kid. Hawaii has its passing showers," the sophomore quarterback said. "So it really doesnt bother me." Bralon Addison returned two punts for touchdowns and Byron Marshall ran for 130 yards and two more scores for the Ducks (4-0, 1-0). The game was played as a strong storm swept across the Pacific Northwest, cutting power to more than 26,500 customers in Oregon. It was a sloppy mess on the field, with eight fumbles -- four for each team -- in the first half alone. The Ducks handled the soggy conditions better, building a 41-3 halftime lead. The wind and rain all but shut down the "Bear Raid" offence that new head coach Sonny Dykes has installed at Cal (1-3, 0-1). Cal freshman quarterback Jared Goff went into the game as the national leader with an average of 435.3 yards passing a game. He completed just 3 of 6 passes for 11 yards in the first quarter before he was replaced with backup Zach Kline. Goff, making his first start on the road, simply couldnt grip the ball. "The ball was slipping out of his hand. Were not quite sure why but it was," Dykes said. "So we felt like were having a hard time getting anything done. Couldnt throw it at all. We needed to make a change and it felt like it gave us a better chance to move the football and score some points." Mariota, whose name is mentioned as an early Heisman Trophy candidate, completed 11 of 24 passes for 114 yards and ran for another 33 yards before coach Mark Helfrich sat him during the third quarter. Oregon coach Mark Helfrich also suggested Mariotas Hawaiian upbringing had something to do with his ability to shake off the storm. "Playing on the beach as a kid, I thing, was paying off," Helfrich said. Oregon opened the game with Marshalls 14-yard scoring run. Mariota threw two touchdown passes, a 19-yarder to Josh Huff and a 14-yarder to Daryle Hawkins before Marshall ran for a 25-yard score to make it 27-0. But the start of the game was also costly for Oregon. Running back DeAnthony Thomas was hurt while returning the opening kickoff. He grasped hiss lower right leg and had to be helped off the field. Real Madrid Futbol Shirt. He reappeared after the half on crutches, but because Oregon does not discuss injuries it is unclear how serious it is. Afterward, Thomas said he hurt his right ankle, but it had not been X-rayed. He said he was trying to make a move but "it was slippery out there." "Im very focused," said Thomas, who was uncertain about his status for next weeks game at Colorado. "Ill get back there when I can." The speedy junior leads the Ducks with 338 yards rushing and six touchdowns. He has 485 all-purpose yards through Oregons first three games. Mariota ran 2 yards to score in the second quarter before Addisons 75-yard punt return for a touchdown. Cal finally got on the board as time ran out with Vincenzo DAmatos 46-yard field goal. Addisons 67-yard punt return for a score early in the second quarter made is 48-3. The only other Duck with two punt returns for touchdowns in a game was Cliff Harris against New Mexico in 2010. Thomas Tyner ran for a 21-yard touchdown for the Ducks before Jeffrey Coprich pushed in a yard for a TD for Cal to make it 55-10. Kline hit James Grisom with a 7-yard scoring pass for the final margin. Kline completed 18 of 37 passes for 165 yards. Ducks defensive co-ordinator Nick Aliotti likened the weather to the so-called "Toilet Bowl" between Oregon and Oregon State in 1983, the last college game to end in a scoreless tie before the NCAA changed its rules. "Those conditions were pretty terrible," Aliotti said. "But I dont know if it was as windy." Both teams were coming of bye weeks. The Bears last outing was a 52-34 loss to No. 4 Ohio State on Sept 14. The Ducks are the third ranked opponent that Cal has faced; the team also lost to then-No. 22 Northwestern in the season opener. All three teams are undefeated. Oregon put up easy nonconference victories over Nicholls State, Virginia and Tennessee. The Ducks have averaged 61.3 points per game, ranked second nationally, while allowing opponents just 9 points a game. Cal hung close with Oregon for a good part of their last meeting, trailing just 24-17 midway through the 3rd quarter last year. But Mariota led the then-No. 3 Ducks on a 35-0 run for a 59-17 victory in Strawberry Canyon. He matched a school record with six touchdown passes in that game. ' ' '
