It is a shame the Wankhede got nothing. It is the MCG and the Lord's of India. OTOH, Visakhapatnam is lucky to get not one but TWO playoffs! Really, Chinnaswamy and Wankhede should have got at least one playoff each.
If eliminator & 2nd playoffs happens in two different venues then the team playing that games have to travel to 3 different venues in five days if they reach finals too so it will be too tiring for them whereas winner of 1st playoffs gets that 5 day to relax & get used to final venue. So always eliminator & 2nd playoffs take place in same venue
