3:30 p.m. Harbhajan Singh wins the toss and Mumbai Indians are bowling. Both captains wanted to bowl as both are uncertain how the fresh track would play.
3:15 p.m. If it were last year, we would have touted today's battle at the Wankhede as the one between the top contenders of the IPL. But this is not 2011. We are in 2012 and this is IPL 5, and the form of defending champions Chennai Super Kings and CLT20 winners Mumbai Indians is nowhere near as any of the previous four seasons.
While the two big guns have somehow managed to stay in the top four at this juncture, their form doesn't instil any confidence in their fans. But a win today will do a world of good to not only their chances for the playoffs but also to win back the fans they seem to be losing fast.
Talking about the match prospects, here is our preview that you can dig into as we approach time for the all-important toss.
