MONACO -- Sebastian Vettels season got even more frustrating on Sunday after the four-time defending Formula One champion spent most of the Monaco Grand Prix watching from the garage after car failure ended his race. The German driver had already won two races by this stage last season, but this year he has only one third-place finish and is down in sixth overall behind Nico Hulkenberg and Daniel Ricciardo. Not helping matters, Vettels Red Bull teammate Daniel Ricciardo has back-to-back third places in Spain and in Monaco. The Australian driver seems much more at ease than Vettel with the engine regulation changes that came in at the start of the season. "I felt quite helpless in the car, so I was asking for an answer of what we could do, but there wasnt anything at that stage," Vettel said. "Its disappointing. I had a good start and then we lost boost pressure from the turbo, so I had no power and had to retire." Vettel moaned "come on guys" over the race radio when he was called into the pits, before changing tact with a more diplomatic "I mean youre trying everything." He had also complained of being "stuck in first gear," and team principal Christian Horner moved to reassure his star driver afterward. "First of all we have to apologize to Sebastian for an issue with his power unit," Horner said. "Its frustrating that, after making a good start, his race came to a very premature end." It is some contrast to last season, which Vettel rounded off with nine straight wins. He won 13 of 19 races and looked untouchable, retired only once -- at the British GP -- and finished on the podium 16 times as Red Bull crushed all the opposition. "We will move forwards, and it will be good for us soon," said Vettel, who also retired from the season-opening Australian GP. Ricciardo is nine points ahead of him heading into the Canadian GP in two weeks time. 76ers Jerseys China .

LAS VEGAS -- Dutch heavyweight Stefan (Skyscraper) Struve, slated to make a comeback Saturday after a heart scare, was scratched from his UFC 175 bout with Matt Mitrione after blacking out while warming up. "Stefan Struve suffered a non-life-threatening, near-fainting spell backstage," the UFC said in a statement during the fight card. "Afterwards, the medical team did not feel he was fit to compete. With his health and safety in mind, hes been removed from the card and is currently under the care of the medical staff." After the card, UFC president Dana White said Struve was "doing great" and had been cleared by doctors. "He had something like a panic attack," he told the post-fight news conference. "He almost blacked out, he started hyper-ventilating, his blood pressure dropped. I dont know, just one of those weird things." White said Struve had to ponder his fighting future. "He needs to do some soul-searching. Hes a super-talented guy. Hes a great guy, we love the guy. I dont know, well see where he goes from here." Struve, meanwhile, tweeted he was fine. "Just want to let everybody know Im OK, had a blackout in the locker room and we had to call the fight off, thanks for the love folks!" White said both Struve and Mitrione would get their basic purse. "I found out what happened and went to talk to Stefan," Mitrione said in a statement. "He was still in his chair and was very apologetic. Hes such a competitor. Obviously health and safety come ffirst.dddddddddddd" The six-foot-11 Struves MMA career appeared over last year when he was diagnosed with a rare heart condition. Given the OK to resume fighting by his doctors in the Netherlands and the UFCs cardiologist, Struve (29-6) was looking forward to returning to the cage. Struve was also cleared by the Nevada State Athletic Commission. "It looks good," Struve said in a pre-fight interview, "I just need to do checkups two times a year with my doctors in Holland and two times a year with my doctors in L.A. "Thats no problem for me. I actually like that I know for sure that my heart is healthy." The 26-year-old Struve, ranked 12th among heavyweight contenders, last fought in March 2013 when he suffered a broken jaw in a knockout loss to hard-hitting Mark Hunt in Japan. He returned to training some three months later. But he blacked out briefly while at his parents home and went to hospital to be checked out. A stress ultrasound test, which uses high frequency sound waves to examine the hearts anatomy and function, found the heart issue. Struve was diagnosed with a leaking aortic valve, as well an enlarged heart. It meant that his heart was only pumping 60 per cent of his blood into the aorta and then the rest of his body. The remaining 40 per cent was ending up back in the heart chamber. Doctors used medication to control his blood pressure and the demands on his heart. Struve says he will probably have to undergo surgery at some point but hopes to do it after his fighting career. ' ' '
