A quick look at teams success while chasing (Batting) more than 150 runs in current IPL. Punjab has immaculate record of 100 % success, followed by Chennai who manage 3 win in 4 games.
Kolkata and Mumbai were asked to chase 6 times, and succeeded 4 times.

Top 4 Batsmen contribution: the 2nd column in this table shows % contribution by top 4 batsmen in each team. Kolkata’s top 4 have contributed the most, followed by Hyderabad and Chennai.
Interestingly while chasing 150, both Punjab/ Mumbai top 4 have contributed less, it’s their middle and lower order which has successfully chased down these targets. Maybe that is one of the reason Punjab is scoring 10.29/ over (highest run/rate).
Boundary rate: Punjab’s rate is excellent, on average 15 fours/100 balls, and 8 sixes/100 balls. Kolkata surprisingly has the least six hitting percentage, 4/100 balls!.
