Mumbai: After rediscovering his form with a stroke-filled half century, Yuvraj Singh rued that his team Delhi Daredevils could not deliver the knock-out blow on the Mumbai Indians despite reducing the hosts to 40 for 4 and lost the crucial IPL cricket game.

"We had them (reeling) at 40 for 4. We should have won the game from there, but we didn't pick up wickets," said Yuvraj at the post-match presser after MI won by five wickets with three balls to spare at the Wankhede Stadium here.
