bLewis Hamilton has admitted Mercedes may not have fixed the fault that has caused his engine to break down twice in the opening four rounds of the season. Ahead of this weekends Spanish GP, Mercedes have described finding a solution to the MGU-H failures which affected Hamiltons car in qualifying in both China and Russia as their highest priority.However, the world champions have been unable to offer Hamilton any guarantees that the problem - described by team boss Toto Wolff as a freak occurrence - will not occur again. The team have explained the issues we have had and the efforts they have made to rectify them, Hamilton told Sky Sports F1. They arent rectified but they are in the process of being rectified. Hopefully this weekend they will be rectified but that might not be the case. Trailing Nico Rosberg by 43 points in the standings, Hamilton has described the deficit as a mountain but insisted he is relishing challenge of trying to catch his team-mate. It is what it is, theres no point being concerned, he said. I have less engines than Nico, so Ive just got to do what l can with what l have. For sure, I have a mountain to climb, but l love a challenge and I am excited about it.Who is under the most pressure this weekend in Spain?The world champion has also vowed he has no concerns about his Mercedes garage crew after the teams decision to swap personnel over the winter coincided with a series of mechanical malfunctions on his car. The issues we have had are nothing to do with the mechanics, said Hamilton. That is not a concern. I have 100 per cent belief in the guys and the team. I am just hoping l have had my share of bad luck.While Hamilton has bore the brunt of Mercedes reliability glitches so far in 2016, Rosberg has reeled off four successive victories to establish a commanding early lead in the Drivers Championship.But, despite his run of wins from the final races of last season now stretching to seven, the German remains unmoved in his belief that nothing is won yet. Ted Kravitz thinks Mercedes have to sort out their mechanical problems at the Spanish GP if Lewis Hamilton is to have any chance of winning the drivers championship Its not difficult to keep the feet on the ground, you just need to look at reality, he said. Lewis is still the same Lewis as the last two years. Hes still just as quick and just as difficult to beat. Thats it.Its a long, long way to go.It wouldnt be good for me to think seven months down the road. The best way for me to try and win Barcelona is to think about Barcelona. And thats my aim, to win Barcelona. Thats the way I like to approach it and its the best approach for me.Rosberg led large parts of the 2014 season before Hamilton eventually overhauled him, but his championship advantage never exceeded 29 points. This time his lead is nearly the equivalent of two race victories but Rosberg, runner-up to Hamilton in each of the last two years, denied suggestions 2016 now presented him with an opportunity of a lifetime to become world champion. Fernando Alonso and Lewis Hamilton react to the news of Daniil Kvyat and Max Verstappens swap Im 30 now and still a young F1 age Id like think, he said. So I dont think that way and have such thoughts.Im just in a great situation which Im enjoying. I have the opportunity to win races - winning is a massive thrill and thats what I race for. [I am] up against some awesome drivers. Up against Lewis and the red guys, Kimi [Raikkonen] and Vettel. Some great battles and it makes it all the more fun when I win races, especially in a straight battle.Watch the Spanish GP live on Sky Sports F1.

Wednesday night, he was able to do both in the same inning to help the Cincinnati Reds pin a frustrating loss on two-time Cy Young Award winner Clayton Kershaw. Phillips and Homer Baileys seven effective innings led the Reds to a 3-2 victory over the Los Angeles Dodgers on Wednesday night. "Regardless of who was pitching, it feels good just to come through for the team and do something positive to get us going in the right direction," Phillips said. "We havent been really scoring that many runs and havent been getting many clutch hits. Kershaws one of the best pitchers in the game, but tonight we just hit some mistakes." Phillips, a four-time Gold Glove second baseman, robbed Andre Ethier of an RBI single when he made a diving stop of his grounder in the hole and threw him out after a leadoff double by Dee Gordon. Bailey escaped the inning unscathed by striking out Yasiel Puig and Hanley Ramirez. "I feel like defence wins championships and offence sells tickets," Phillips said. "That defensive play I made really saved the game. Im surprised I got to that ball. I didnt really see it come off the bat really good." Bailey (5-3) allowed two runs and five hits while striking out six. The right-hander has won consecutive starts for the first time this season following his 5-3 victory over St. Louis last Friday. "It was good for me, especially with the April I had," Bailey said. "Obviously its not how I wanted to start the season. It took a little while to get my legs underneath me. I would have liked to put up a few more zeros, but doing it against Clayton -- and the fact that we scored three runs -- you just make sure you lock them down. It was a really big win. We needed that one. You dont ever want to get swept. I dont care where youre at or who youre playing." Ethier, who drove in a season-high four runs Tuesday night, was 0 for 3 against Bailey and is hitless in 21 career at-bats against him with seven strikeouts. "He was just moving the ball so well," Ethier said. "Hes one of those guys who can be wildly effective at times, and other times he can spot up a pitch and throw something in there at 93-944 -- then reach back for 96-97 -- and its moving all over the place.dddddddddddd He can throw his other pitches for strikes, too, so its a tough combination. In the past, Ive seen a lot of cutters from him, and tonight I didnt see one. It was all two-seam fastballs and one breaking ball." Puig, who has reached base safely in 29 straight games, led off the Dodgers sixth with an opposite-field homer to right-centre that narrowed the gap to 3-2. But former Dodgers closer Jonathan Broxton retired Puig and Ramirez on flyballs for the last two outs in the eighth after replacing Manny Parra with a runner at second, and Aroldis Chapman pitched a perfect ninth for his fifth save. Kershaw (3-2) allowed three runs and seven hits in seven innings and struck out nine. He retired 14 of his next 16 batters after Phillips homer. The left-hander, who led the majors in ERA in each of the previous three seasons, has a 3.57 mark through his first six starts this year. He missed all of April because of a strained muscle in his back, after beating Arizona March 22 during the Dodgers season-opening two-game trip to Australia. Matt Kemp, who hadnt started a game in left field since his rookie year, was back there Wednesday on the eighth anniversary of his major league debut. It was his eighth career start in left, and first since June 21, 2006. Todd Frazier doubled over Matt Kemps head leading off the sixth and scored on a wild pitch to give Cincinnati a 3-1 lead. Only one of the last 34 home runs Kershaw has given up has been with more than one man on base. That was a three-run shot by former Seattle catcher Miguel Olivo, who eventually joined the Dodgers in January as a free agent -- and was released last week after biting off a piece of Triple-A Albuquerque teammate Alex Guerreros left ear during a dugout brawl. NOTES: Hall of Fame broadcaster Vin Scully was back in the Dodgers TV booth after missing two games because of a chest cold. ... Canadian-born OF Jamie Romak, promoted from Triple-A Albuquerque because of Crawfords injury, pinch-hit for Kershaw in the seventh and grounded out to second on the first pitch he saw in the major leagues. ... Dodgers RHP Brandon League retired both batters he faced. He hasnt allowed an earned run in a career-best 22 innings spanning his last 16 appearances. ' ' '
