Agreed, the team that were able to reach 100 runs in the 11th over unable to score another 77 runs in 56 balls is really poor batting performance. Simple, the team is much depending on few players. I haven't gone into the statistics, but in most of the Matches in which Suryakumar Yadav played well is a win for Mumbai Indians. Today even with the best batsmen on the crease and unable to win scoring 11 runs in the last over is a big disappointment for the Mumbai Indians team supporters.
Mumbai failed to do the most basic thing in the last match. They should have made sure that Tim David gets the strike for a maximum number of deliveries. But the opposite happened. In the last over, he got to face just 1 out of the 6 balls. David was in fine form, and in the 19th over (which was bowled by Naveen-ul-Haq) he managed to score 19 runs. If he faced Mohsin Khan during the last over instead of Cameroon Green, then Mumbai would have won the match easily. But a lot of things went wrong for Mumbai in the last 4 overs, beginning with the decision to send Vishnu Vinod ahead of Green and Jordan.
