With the lose againt Bangalore, the chance for Chennai reaching semi goes down a log. Of the Four team contending (Chennai, Mumbai, Delhi and Kolkata) for last two in Semi, Chennai is having a very low runrate. Unless Chennai beat Rajasthan and Deccan, then cant move up with the number of wons to select for semi. With they loosing to Bangalore this bad, I believe they are going to loose to Rajasthan. Being that case, it will be Mumbai and Delhi in semi. Unless Delhi and Mumbai did something very wrong.
