Who will be the other 2 Semifinalists

Even though RCB lost the match by a huge margin, their NRR remains at +0.219. Which in any way you calculate makes them to reach SF along with MI. This they have to thank for their 2 huge wins against RR and a good win against KKR. Otherwise they would be sitting with crossed fingers.

Now the race narrows down to 2 SF spots. Among DD,DC,CSK,RR and KKR, the first three have their fate on their hands whereas the other 2 depend on others result also.

RR will know their fate today. They have scored only 132 which will make their case even more difficult. For their chance, they have to knock out KKR within 100 runs and hope for other results to be favourable to them.
- Heavy defeat for DC and a defeat to CSK.

KKR have to play out of their skin to sniff any chance of reaching SF. Today they have to achieve the target within 10 overs and also win their game against MI either by atleast 100 runs or with 10 overs remaining. Which is very unlikely to happen
- Heavy defeat for DC/DD and a defeat to CSK.

Both the above cases are pretty unlikely to happen. Let us see the following teams.

For DD and DC it is virtually a QF, whoever wins goes through to SF with 16 points. A heavy defeat for either of them will virtually shut them out of the competition.

DD, even if they lose there is a minor chance for them to progress, provided,
- A very narrow defeat for them, a defeat to CSK, a narrow win for RR.

DC, they have to win at all costs to go to SF. If they lose they are going out of the tournament. But there is a very very slim chance for them if they lose.
- A very narrow defeat for them, a defeat to CSK, a lose for RR and a lose for KKR against MI. This is a very high probability to happen.

CSK, very simple, win and proceed to SF. There is no other permutations and combinations.

So overall, MI at 1st place, DC/DD at 2nd place, if CSK wins 3rd place and RCB 4th. Otherwise 3rd place for RCB and anyother team will be in 4th place.
