BARCELONA, Spain -- Nico Rosberg will use his frustration from the Bahrain Grand Prix for motivation when he starts the Spanish Grand Prix from pole position Sunday. The German driver finished ahead of Lewis Hamilton to give Mercedes front-row seats at the Circuit de Catalunya, with both drivers still seeking their first wins of the season in a car which has plenty of pace but has lacked durability over the first four races. Three weeks ago, Rosberg took pole in Bahrain only to finish ninth, and he is determined not to fall short again. "We know that this is only half of the job completed and have the painful memory of what happened in Bahrain to prove that," said Rosberg, who is chasing his first podium this season. "Weve worked very hard on our race pace but this track is tough for the tires, particularly with graining. It will be a big challenge tomorrow and our goal is to make the most of the opportunity from starting at the front." While Hamilton had the fastest times in the first two qualifying sessions, Rosberg edged him to win the pole position in 1 minute, 20.718 seconds. Three-time defending champion Sebastian Vettel was third quickest. "It will be a big challenge with the tires tomorrow," said Rosberg, whose best result this season was fourth at the Malaysian GP. "The race is very long and to win its not good enough to start from pole -- you still have to have the fastest race car." Hamilton, the 2008 Formula One champion, is unsure how much to read into his teams qualifying speed. "Ive not been totally happy with the balance of my car all weekend, even today, so we need to look at it this evening and see what we can do for the race," the British driver said. "Limiting the degradation is going to be my major challenge as the general pace isnt too bad." Vettel was satisfied enough with his performance as he finished ahead of Kimi Raikkonens Lotus. "Im quite happy to be honest because yesterday and this morning I wasnt really happy. We improved the car and things calmed down," said Vettel, who has 38 career poles but none in Barcelona. "Its a tough challenge and the tires dont last as well as we would like." The degradation of the Pirelli tires has been an issue all season, and drivers are largely unhappy about how quickly they wear out. Ferrari has yet to secure a pole position this season, and it proved to be another frustrating afternoon for the Italian team after fast practice times in the morning. Fernando Alonso will start fifth and Felipe Massa ninth. Massa finished sixth in qualifying but was bumped down three places for blocking Red Bulls Mark Webber on turns 11 and 12. Jenson Button failed to make the cut for the third session. The Briton will start in 14th place, with teammate Sergio Perez in eighth. "Weve had a difficult couple of days. I had problems throughout practice, so to get through to Q3 was a great result, and something we really werent expecting," Perez said. "Im very pleased because I got absolutely everything out of the car." Earlier, Massa was fastest in the third and final practice session ahead of Raikkonen. Webber was third in final practice but had a poor qualifying session and will start from seventh place, behind Lotus Romain Grosjean. They moved up a place due to Massas grid penalty, as did Perez. "I was disappointed with the lap in Q3 and lost a lot of time in the last sector," Webber said. "Im normally quite strong there, but I was in trouble with the rears." Ferrari wants its drivers to find extra speed in qualifying to increase the pressure on Red Bull. Once again, those hopes were unfulfilled. The closest Ferrari has been to pole was when Massa qualified second in Malaysia. Alonso started the previous three races from third. Mercedes has been fast but lacking durability this season, so Hamilton and Rosberg stayed on longer runs than other drivers in practice. "Its going to be tough to keep these positions tomorrow," Hamilton said.

LOS ANGELES -- UCLA dropped offensive coordinator Kennedy Polamalu on Sunday after a dismal season for the Bruins offense.Coach Jim Mora announced the move one day after his worst year in Westwood ended at 4-8 with a loss at California.Polamalu spent just one season calling plays for the Bruins offense after two years as their running backs coach. The veteran assistant was promoted and promised to bring a physical, run-based pro scheme to the school after four seasons under Noel Mazzone, who ran a sophisticated college-style passing game.Instead, UCLA finished 127th out of 128 FBS teams with just 84.3 yards rushing per game. The Bruins also did little with talented sophomore quarterback Josh Rosen, who will have his third offensive coordinator in three seasons next year after missing the second half of this season with injuries.I want to thank Kennedy for his hard work, dedication to the program and commitment to our student-athletes, Mora said in a statement announcing his move. He is a professional in every sense of the word.After starting the year as an AP Top 25 team and the favorite to win the Pac-12 South, UCLA finished with its worst season record since 2010, which is also the last time the Bruins missed a bowl game.UCLA finished 92nd in the FBS in total offense and 96th in scoring offense after de-emphasizing itts ineffective running game later in the season.dddddddddddd Replacement starting quarterback Mike Fafaul, a former walk-on, set school records with 70 passes and 40 completions while running a spread offense during a shootout loss to Utah last month.Polamalu remained the Bruins running backs coach this season while also taking over play-calling responsibilities. He later adjusted his sideline duties, saying he didnt have enough time to give key coaching to running backs Soso Jamabo, Bolu Olorunfunmi and Nate Starks.Paul Perkins was a 1,000-yard rusher for the Bruins in 2014 and 2015, but UCLA managed just 1,011 total yards rushing this season.Polamalu was Mazzones running backs coach for the previous two seasons at UCLA. He was the offensive coordinator and running backs coach at crosstown rival Southern California from 2010-12 under Lane Kiffin, who called the Trojans plays.Mora is 41-24 in five seasons at UCLA, with two 10-victory seasons and two bowl wins in his first significant college coaching job.
