"We have done some upsets at World Cups but we want to prove something at this tournament." <p></p> <p></p>Meanwhile an elated Mortaza added: "Mushy always plays that kind of innings, and Shakib batted so well. <p></p> <p></p>"We knew we had to bowl in the right areas. We were able to get wickets in patches," added Mortaza, who thanked the Bangladesh fans for their support. <p></p> <p></p>In contrast, South Africa are in turmoil after Du Plessis' decision to bowl first backfired despite two wickets from veteran spinner Imran Tahir in his 100th ODI appearance.

The skills weren't here today but I can promise there will be fight against India on Wednesday. <p></p> <p></p>"We're only firing at 50-60 percent and it shows than even Bangladesh can beat that." <p></p> <p></p>Quinton de Kock and Aiden Markram needed to get South Africa's chase off to a fast start and they reached 49 before a disastrous blunder sent them spiralling towards defeat. <p></p> <p></p>De Kock was run out for 23 after being rashly called for a single by Markram, whose partner's edge was fumbled by Mushfiqur before the wicket-keeper recovered to throw out the opener. <p></p> <p></p>That brought Du Plessis to the crease and together with Markram he put on 53 in 60 balls. <p></p> <p></p>But Shakib curtailed that partnership when his perfectly-flighted delivery bowled Markham for 45 to leave South Africa 102 for two in the 20th over. <p></p> <p></p>That made Shakib just the fifth player to score 5,000 runs and take 250 wickets in ODIs. <p></p> <p></p>Du Plessis completed a 45-ball fifty with a six off Mosaddek Hossain. <p></p> <p></p>But that blast got du Plessis' adrenaline flowing too fast and a charge at Mehidy saw him bowled after he misjudged the flight. <p></p> <p></p>The required run-rate was at 10 an over by the time Rassie van der Dussen's agricultural swipe saw him bowled by Mohammad Saifuddin for 41. <p></p> <p></p>Saifuddin removed Andile Phehlukwayo and when JP Duminy was bowled by Mustafizur for a defiant 45, Bangladesh's jubilant fans could get the party started.
