Chittagong Vikings 161 for 3 (Tamim 54, Malik 42*) beat Comilla Victorians 132 for 8 (Shanto 54*, Nabi 4-24) by 29 runsScorecard and ball-by-ball detailsChittagong Vikings sent out an early warning as they beat defending champions Comilla Victorians by 29 runs in the tournaments opening game. After Tamim Iqbal and Shoaib Malik helped them set up a fighting total, Man of the Match Mohammad Nabi took control of the game with his four-wicket haul.Tamim sped to 50 off 32 balls with his team score on 69 for 1 at the end of the ninth over. But he was having trouble running between the wickets with Anamul Haque and, almost predictably, the second-wicket pair had a meltdown when Tamim ran for a second despite Anamul calling no after pushing to long-on.Tamim, who had been dropped on 23 by Nahidul Islam running back from cover, was furious as he fell for 54 off 38 balls. His knock was studded with two sixes - over long-off and cover - and six attractive boundaries. Anamul was also run out when he backed up too far in the hunt for a single. Marlon Samuels, running in from midwicket, struck down the stumps at the non-strikers end.Chittagongs innings looked in danger of getting derailed, but Malik and Jahurul Islam added 60 runs for an unbroken fourth-wicket stand that took the Vikings to 161. Malik struck two fours and two sixes in his 28-ball 42, while Jahurul contributed 29 off 21 balls. The unbroken partnership meant that Chittagong were deprived of Mohammad Nabis big-hitting prowess in the slog overs, but the Afghanistan allrounder made up with the ball.Nabi removed Liton Das and the dangerous Ashar Zaidi in the eighth and tenth overs respectively, to reduce Comilla to 58 for 4, after Imrul Kayes had fallen early to a reckless waft outside off against Dwayne Smith, and Samuels had chipped a catch to short midwicket off Abdur Razzak.Mashrafe Mortaza, who promoted himself to No. 6 to breathe life into the faltering chase, fell to Tymal Mills and was followed into the dressing room by Imad Wasim four balls later.Nabi picked up his third and fourth wickets off consecutive deliveries in his last over, by bowling Al-Amin and trapping Sohail Tanvir in front. Debutant Nazmul Hossain Shanto (54*), who had watched his team crumble around him after coming in at No. 4, provided some late entertainment for the half-packed stadium, hitting Taskin Ahmed for four boundaries in a row in the last over to bring up his fifty. But it all came too late for Comilla. ABU DHABI, United Arab Emirates -- After finally getting the better of longtime rival Lewis Hamilton to become Formula One champion, the weight is off Nico Rosbergs shoulders and he has the chance to really show what he can do.But at 31, the German driver is already into his peak years and only has a limited time left at the top.Rosberg showed impressive mental resilience to get the better of Hamilton over a topsy-turvy season, and the title victory was even sweeter considering that they have been competing against each other since their karting days as teens.It feels like I have been racing him forever and always he has just managed to edge me out, Rosberg said after clinching the title at the Abu Dhabi Grand Prix on Sunday. He is just an amazing driver and one of the best in history. That makes it so much more satisfying that I took the world championship away from him.For Rosberg to be spoken of alongside other F1 greats, he needs to do more than beating Hamilton over 21 races in essentially the same Mercedes car. He was thoroughly consistent, but Rosbergs title win lacked the wow factor in terms of pure driving.He needs to dominate a campaign the way Hamilton and four-time champion Sebastian Vettel -- and others before them -- have done.Rosbergs tally of 23 career race wins is commendable but unremarkable considering Hamilton -- who is the same age -- has a whopping 53 wins. Vettel, who is two years younger, already has 42.Two-time F1 champion Fernando Alonso, who is for some observers still the most skilled driver in F1, has 32 wins. That total would be far higher had Alonso been given a leading car. The Spaniard has not won a race since taking the checkered flag for Ferrari in May 2013. He has spent this season and last getting the best out of a struggling McLaren adapting to its switch back to a Honda engine.Clearly, Rosberg needs to improve his speed if he is to be considered among the best.This year, Hamilton secured 10 wins to Rosbergs nine and -- as Hamilton has consistently repeated -- would probably have had a couple more wins without engine problems that cropped up several times. He connsiders himself to have been the best driver.ddddddddddddbviously we had a lot of problems this year, and thats inevitably why Im in this position, Hamilton said as Rosberg sat next to him in Sundays post-race news conference.Although Hamiltons comments smacked of poor sportsmanship, he does have an argument.In qualifying, Hamilton took 12 pole positions compared to eight for Rosberg, even though Hamilton was unable to compete in three sessions because of engine woes.Rosberg, however, could also have got more poles under different circumstances.He was not pushing Hamilton in qualifying over the last four races because he was more concerned with protecting his considerable lead and playing it safe on race day, where taking second place behind Hamilton was enough.Still, aside from Singapore, where Rosberg crushed Hamilton in qualifying with a quite stunning lap, he has not been as quick.After missing out on a third straight F1 title and fourth overall, Hamilton will be hugely motivated next year.Others will be pushing Rosberg, too, not least Red Bull driver Max Verstappen.The 19-year-old Dutchman has taken F1 by storm this year -- becoming the youngest to both win a race and qualify on the front row.With rule changes -- notably wider tires -- expected to make the 2017 cars several seconds quicker, Mercedes might be more strongly challenged.Verstappen will have more experience and Red Bull will be confident that he can challenge for wins, considering it was the only team other than Mercedes to win a race this season. Vettel has also expressed optimism that Ferrari can close the gap.Rosbergs father -- 1982 Formula One champion Keke Rosberg -- said his son will need to be ready.The level is always high in Formula One. Look at Max, he is the teammate of (Daniel) Ricciardo. Or Vettel, he is the teammate of (Kimi) Raikkonen, Keke Rosberg said. When you take the top three teams, all of them have been world champions, or at Red Bull theyre all young talents. Thats the level we have. ' ' '
