Rajasthan Royals' (RR) skipper Sanju Samson expressed disappointment after his side lost against Royal Challengers Bangalore (RCB) in the Indian Premier League (IPL) clash on Tuesday. Brilliant display of batting by Dinesh Karthik (44* off 23 balls ) and Shahbaz Ahmed (45* off 26) helped RCB beat RR by four wickets at the Wankhede Stadium here on Tuesday. "I can't point out one moment where we lost the game. I thought it was a great effort to put up that total on such a slow wicket after losing the toss. Jos (Buttler) and (Shimron) Hetmyer batted brilliantly at the death. Taking the match to the last over with the dew coming in was a great effort as well," said Sanju Samson in a post-match presentation.
