Mercedes chief Paddy Lowe has admitted the world champions worry about the threat Ferrari pose to their F1 supremacy ahead of the 2016 season. The top two teams from last season both gave the first glimpses of their new cars on Friday, with Ferrari holding an official unveiling for their SF16-H online while Mercedes completed a shakedown with their new W07.Ferrari say they have taken some innovative steps in an attempt to close the gap, redesigning the front of their car and power unit layout, but Mercedes enter 2016 as F1s undisputed leading force after back-to-back world titles. But speaking after the W07 was put through its early laps at Silverstone, Mercedes executive director Lowe acknowledged the likelihood of an increased challenge from their Italian rivals.We see Ferrari as our main threat and it remains to be seen how we position ourselves in the weeks to come, Lowe told Sky Sports News HQ.Ferrari are a very strong competitor and one we worry about. It keeps us motivated to keep us pushing all the time. Exclusive pictures of the Mercedes W07 - their new car for the 2016 F1 season Nico Rosberg was behind the wheel for the W07s initial laps at Silverstone, before handing over to world champion team-mate Lewis Hamilton in the afternoon.The German is also expecting a more intense battle with Ferrari this year.We take our opposition very seriously - especially Ferrari, Rosberg said. For sure, they are going to be a big threat so we need to keep pushing. Who knows where we are going to be first race?Ferrari launch: New SF16-H is unveiledWith the new Ferrari and Williams cars breaking cover on Friday, and McLaren to follow on Sunday, Lowe admits Mercedes engineers will already be looking out for something they may have missed in the W07s conception.This is a great time of year, he said. One of the games we are all playing behind the scenes is waiting for those launch photos and our aerodynamicists will pour over those to see if there is something interesting or something we havent thought of. Craig Slater catches up with Nico Rosberg at Silverstone Although Mercedes Silverstone shakedown was mainly for filming purposes, and they were were restricted to 100km and running on demonstration tyres, the laps completed would have allowed them to iron out any teething problems with the W07.However, in what could already be considered an ominous sign for their would-be 2016 rivals, Lowe revealed: We havent even taken the engine cover off yet in the whole morning session which is a really good sign of the reliability weve achieved at this point.Today is all about filming and making sure we are able to hit the ground running on Monday when we get into the proper testing and see whether there are any major issues that weve overlooked. But so far so good.

CLEVELAND -- Surrounded by his infielders, Rick Porcello stared at the ground in disbelief.In a dizzying span of nine pitches, the Cleveland Indians had rocked him for three home runs in the third inning.Bostons ace never quite recovered.The Red Sox didnt either.Francisco Lindors homer capped Clevelands three-homer rampage off the 22-game winner, and the Indians held on for a 5-4 win on Thursday night in their AL Division Series opener.Lindor, Jason Kipnis and Robert Perez went deep in the third off Porcello, who lasted 4 1/3 innings in his shortest outing this year as the Indians landed the first shot in the best-of-5 series against David Ortiz and the AL East champions.Thats never how you want to start off a playoff series, Porcello said. It is what it is.Porcellos shaky start made it tough on the Red Sox, who got home runs from Brock Holt , rookie Andrew Benintendi and Sandy Leon but couldnt get the big hit when they need one late.Boston had chances, but stranded the tying run at third in the eighth when Cleveland closer Cody Allen struck out Xander Bogaerts to end the inning. The Red Sox put a runner on with two outs in the ninth, but Allen fanned Dustin Pedroia on a full-count checked-swing , his 40th pitch, for the save.Pedroia was livid at first base umpire Phil Cuzzis call, and Red Sox manager John Farrell went onto the field to question plate umpire Brian Knight.It was a check swing at a ball in the dirt, Farrell said. At real-time, its a borderline call. After you get a chance to look at video, he swung.Pedroia fired his helmet in disgust as he went to the dugout but later said he overreacted.I went, but I just was frustrated with the situation, said Pedroia, who went 1 for 5 and struck out three times. Ill apologize to Phil tomorrow for giving him a piece of my mind.Indians manager Terry Francona, who won two World Series with Boston, went to his bullpen early. Andrew Miller, acquired by Cleveland in a July trade for an October night like this, pitched two scoreless innings for the win. Summoned by Francona in the fifth, the lefty struck out Ortiz with two on to end the fifth and threw a season-high 40 pitches.Ortiz went 1 for 4 with a double in the first game of his final postseason.Boston turns to David Price in Game 2 in the shadows Friday afternoon against Cleveland ace Corey Kluber. Price is 0-7 in postseason starts and unless he comes up big, Big Papi could be closer to saying his last goodbbye.ddddddddddddClevelands barrage off Porcello in the third was breathtaking.Perez started the salvo with just his second homer in 82 at-bats at home this season. One out later, Kipnis drove a pitch over the wall in right-center, giving Cleveland a 3-2 lead and sending the raucous crowd of 37,763 into delirium. Kipnis had just finished getting a celebratory ride through the dugout when Lindors shot to right barely cleared a leaping attempt by Mookie Betts.Porcello was clearly rocked by the barrage, and as Progressive Field shook, he was visited by Pedroia and others who tried to rally their ace.On those three home runs, you can spin it any way youd like to, Porcello said. But the bottom line is this: I threw the pitches that I thought would be the best pitches, and I couldnt keep them in the ballpark.Farrell attributed Porcellos outing to one of those nights.It was a combination of pitches up in the strike zone and a night where this ballpark played extremely small, Farrell said. Warm weather, the ball was carrying a lot. Uncharacteristic for Rick to be up in the strike zone as much as he was. We were probably about the sixth or seventh inning where there were two outs made on the ground. We were up in the strike zone and they made us pay for it.ODD SOX: The teams combined for an ALDS record-tying six home runs. ... Porcello allowed three homers in an inning for the initial time in the big leagues. He made his first postseason start since 2011, falling to 0-3 with a 5.66 ERA in nine career appearances. . Benintendi became the youngest Boston player to hit a home run in his playoff debut at 22 years, 92 days.TRAINERS ROOMRed Sox: All-Star knuckleballer Steven Wright, bothered by bursitis in his right shoulder for weeks, will pitch Saturday at Fenway Park. If all goes well, he will head to the Instructional League and could be added Bostons roster if the Red Sox advance.UP NEXTPrice is 0-7 in the postseason as a starter, a mark that has tarnished the five-time All-Stars splendid career. Kluber will be pitching on 10 days rest. He strained a quadriceps last month and the Indians skipped his last start to give him extra time.They faced each other in 34-degree weather on April 5. Price struck out 10. Kluber allowed four runs, including a two-run homer to Betts, as the Red Sox won 6-2. ' ' '
