The last time this rematch of last year's final happened, both the teams were languishing in middle-and-lower part of the points table. Things have changed since then. Chennai Super Kings have won four on the trot, including that rematch. Rajasthan Royals have come back from that defeat with three straight victories, and now both teams are the joint leaders.
Given the tight nature of the event, we will surely have a new leader by the time Chennai and Rajasthan face each other again tomorrow, the second game of the day. Then again we might not if Delhi Daredevils and Deccan Chargers both lose their matches. But what's certain is that both Chennai and Rajasthan will be in the top four. What's also certain is - more importantly - that by the end of tomorrow, the teams closest to them will have matches in hand. In that light, it's needless to say how important two points will be for both the teams.
Form guide (completed matches, most recent first)
After describing his batting form as "pathetic", MS Dhoni has now become part of a dangerous Chennai trinity, the other two being Matthew Hayden and Suresh Raina. Between them they have scored 895 runs, the rest have scored 391.
In two matches Amit Singh has taken seven wickets at four runs per wicket and has given away runs at 3.5 an over. But as with Rajasthan's earlier prodigy Kamran Khan, Amit's action is also under suspicion.
Watch out for
Chennai: (probable) 1 S Badrinath/M Vijay/Parthiv Patel, 2 Matthew Hayden, 3 Suresh Raina, 4 MS Dhoni (capt. & wk), 5 Albie Morkel, 6 Jacob Oram/George Bailey, 7 Shadab Jakati, 8 Sudeep Tyagi, 9 L Balaji, 10 Manpreet Gony/Joginder Sharma/extra batsman, 11 Muttiah Muralitharan.
It's unlikely Rajasthan will drop Amit. Lee Carseldine, Naman Ojha and Abhishek Raut have been good additions late in the season. It should be touch and go between Morne Morkel, who got his first game when he played against Royal Challengers Bangalore, and Dimitri Mascarenhas.
Rajasthan: (probable) 1 Graeme Smith, 2 Naman Ojha (wk), 3 Lee Carseldine, 4 Yusuf Pathan, 5 Ravindra Jadeja, 6 Niraj Patel, 7 Abhishek Raut, 8 Shane Warne (capt.), 9 Dimitri Mascarenhas/Morne Morkel, 10 Amit Singh, 11 Munaf Patel.
