Mumbai Indians captain Rohit Sharma said his side are known to keep opponents on their toes and that is what will keep the team going in the IPL 10."Winning the game was important. We're known for this -- we keep people on their toes," Sharma, whose side pulled off a stunning four-wicket win after tottering at 119/5 at one stage chasing 179, said at the post-match presentation ceremony."I am very happy with this win. Here at Wankhede, we back our players to get the runs with the dew coming in and the flat pitch."We were hoping (Nitish) Rana and Hardik would finish it off and they did."Rana top-scored for the hosts with a brilliantly paced 50 off 28 while Hardik hit the winning runs with his important 11-ball 29 cameo."It's important for any team to have young players come in like that and finish the job."I hope they repeat it. There's still room for improvement. We don't want to be in the back seat. We know the things we didn't do well today and we'll go back to the drawing board before our next game," Rohit said.This was Mumbai's first win of the campaign after they lost in the opening game to Rising Pune Supergiant.
