New Delhi, May 23:With the rain playing killjoy, threats of a downpour -- and not the blazing blades of Sachin Tendulkar or Sanath Jayasuriya -- remain the cloud on the horizon for Delhi Daredevils in their now-or-never Indian Premier League tie against Mumbai Indians here tomorrow.

The Daredevils found them at the receiving end of the weather god's vagaries in their home match against Kings XI Punjab. Skipper Virender Sehwag lit up the May 17 match with his batting pyrotechnics before heavens opened up and the hosts went down via Duckworth-Lewis method in the rain-truncated encounter.

And it was worse yesterday as their match with the Kolkata Knight Riders was washed away without a ball being bowl.

While it slammed the semifinal door on the face of the Kolkata side, the Daredevils didn't benefit either and nothing short of a win in their final league match tomorrow can see them through to the last-four stage.

With 13 points from as many outings, the Daredevils are placed fourth on the table, while Mumbai trail by just one point, having played 11 matches so far. A win tomorrow would swell Delhi's tally to 15 but the visitors can still pip them to the post if they win their last two matches.

And a washout tomorrow would mean Mumbai would need to win just one match to breeze into the semifinals.

As skipper of the home side, Sehwag would be saddled with a brittle middle order, even though he tries to gloss over the side's over-reliance on the top order.
