Guptill.Nicholls struggled, scoring only seven before becoming Mustafizurs first victim

SPA-FRANCORCHAMPS, Belgium -- While Formula One leader Lewis Hamilton expects to swallow a severe grid penalty at the Belgian Grand Prix this weekend, Mercedes teammate Nico Rosberg hopes to take advantage.Hamilton won six of the past seven races to turn a 43-point deficit into a 19-point lead heading into the summer break.But, after being hampered by mechanical woes during the early part of the season, the British driver has used up his five allotted engine component parts, including the turbo charger. That means he must take on new components, either here or at the Italian GP next weekend, leading to a grid penalty and demotion to the back of the grid.As far I am aware we will be taking the penalty here. I have no engines left, Hamilton said on Thursday. We already discussed engine penalties before and that will come into play, but I will do everything I can to minimize the damage.Mercedes has yet to confirm whether the penalty will be taken in Spa, where a win for Rosberg would give him 25 points and, depending on Hamiltons result, even out the championship standings.Of course Im aware of Lewis misfortune having to get the grid penalty, and thats going to make the weekend less difficult for me because hes my biggest rival, Rosberg said. It doesnt change the pressure I would put myself under.Although starting from the back of the grid all but rules out the chance of a 50th career win for Hamilton in Spa, the nature of the track -- one of the best for overtaking -- gives him a better chance of points than he would get in Monza next week.Hamilton started from the back in China and finished seventh. Two years ago in Hungary, he started from the back and finished third. But he thinks rivals Red Bull and Ferrari are faster than they were back then.Its going to be harder than it was last year or the year before to climb through the field, Hamilton said. Honestly, I really dont know how far I can get. I started last in Hungary a couple of years ago when the gaps were much bigger. Sunday is going to be a lot harder.Chasing his first F1 title, Rosberg has appeared to wilt under pressure over the past few races, handing the initiative back to Hamilton.A third straight year as runner-up to Hamilton -- his rival since they were racing karts as teenagers -- would be unbearable for Rosberg, after winning the opening four races of the season.Last year, Hamilton won here from pole -- five years after his other win -- and Rosberg was second after recovering from a poor start.Stretching through the Ardennes forest, the Spa circuit is the longest of the year at just over seven kilometers (four-plus miles), features famed corners such as Eau Rouge and Blanchimont, an incredibly steep hill, and moody weather that can leave one part of the track damp and another part dry.These ingredients make it arguably F1s most pure test of drivers pure skill, and is regularly cited alongside Japans Suzuka as the race they enjoy most.Unlike another iconic track in Monaco, which is twisty, sinewy, notoriously slow and tough to overtake on, Spa is incredibly fast with more than 70 percent of the race at full throttle and average speeds around 230 kph (143 mph).That will give Hamilton hope of scoring some significant points, even if he does start last.With a bit of luck and safety cars at the right moment, theres no reason why he cant come back through the grid, Rosberg said. Especially on a track like here. New Zealand finished the Super 10s of the World T20 unbeaten after thrashing Bangladesh by 75 runs in Kolkata, a win that ensures top spot in Group 2. Ish Sodhi (3-21) and Grant Elliott (3-12) took three wickets apiece as Bangladesh crumbled to 70 all out in 15.3 overs, chasing 146 to earn a consolation win.Kane Williamson top-scored for New Zealand with 42 from 32 balls - including five fours and one six - on a surface many batsmen struggled on.Mustafizur Rahman took tournament-best figures of 5-22, four of his wickets bowled, including two in New Zealands final over to see him on a hat-trick - but Mitchell McClenaghan blasted that ball for six to push the Black Caps score up to 145-8 with the final ball.Having already secured a semi-final spot with wins over India, Australia and Pakistan in their first three games, New Zealand made two changes, with Nathan McCullum and Henry Nicholls replacing the rested Adam Milne and Martin Guptill.Nicholls struggled, scoring only seven before becoming Mustafizurs first victim. He was replaced by Colin Munro, who also found the going tough early on in his innings, before eventually tallying 35 from 33 balls.Williamson batted nicely at the other end, accounting for 42 of New Zealands first 57 runs before he too was bowled by Mustafiizur.dddddddddddd Williamson plays a shot as wicketkeeper Sarfaraz Ahmed (left) looks on Just when Munro was warming up, lofting Al-Amin Hossain (2-27) into the stands for his second six, he had his middle stump removed later in the same over.Ross Taylor added a useful 28 off 24 balls, but wickets continued to fall around him, with no other batsman managing double-figures.Bangladeshs reply started badly with the in-form Tamim Iqbal run out for three in the second over, and while Mohammad Mithun and Sabbir Rahman struck fours in Mitchell Santners fifth over, thats about as good as it would get for the Tigers.They wouldnt manage another boundary for another nine overs, losing nine wickets for 41 runs, with Sodhi and Elliott particularly devastating with the ball.The only thing that delayed New Zealands charge to victory was a floodlight failure at the ground that brought the players off briefly midway through Bangladeshs innings.Watch highlights of New Zealands win over Bangladesh at 6pm on Sky Sports 2.
