I think yesterday's Dhoni's propmotion up the batting order was really a master stroke. . It achieved two things 1) It shielded Yuvraj from Murali and the SL Spin bowlers as we know yuvi doesnt play spin well. Also Yuvraj off late has been throwing away his wicket and even if he had scored a 20-30 and then thrown away his wicket it wudnt have been good enough. another wicket at that stage could have caused some panic 2) Raina also calmed down and played patiently with Dhoni. remember Raina was dropped before when battng with Gambhir. both did not fear about the run rate and kept working singles and twos well and ran well preserving their wickets. This enabled them later to accelerat well knowing that we still have yuvi-rohith to come unlike the last match(dhoni-rohith accelereted very late as we were 4 down already). Even ater loosing dhoni-raina and quick succession, yuvi -rohith kew that they had to just get 50-60 odd which on this wicket was a cake walk. I think it was a fearless approach from Dhoni to come up the order to control the mid-overs well. he ran his twos and threes well considering the fatigue the guys wud have had after 2 consecutive days against non-minnow oppositions in that heat.
