From Cricinfo: RCB v PBKS is heavily in favour of Punjab:
Kagiso Rabada has a great record against the RCB batters. Against Faf du Plessis: 16 runs in 13 balls, two dismissals. Against Virat Kohli: 27 runs in 24 balls, three dismissals. Against Glenn Maxwell: 23 runs in 20 balls, two dismissals. Against Karthik: 14 runs in 19 balls, three dismissals.
Harpreet Brar has been Kings' go-to bowler in the middle overs (7 to 16). Among those who bowled at least ten overs in that phase last season, Brar's economy of 6.18 was the best. He has a favourable match-up against Maxwell, dismissing him three times in 14 balls. But du Plessis has taken him for 79 runs off 46 balls without getting dismissed.
Jonny Bairstow has a strike rate of over 200 against each of Mohammed Siraj, Karn Sharma and Maxwell. He has a combined 101 runs in 42 balls against them without getting out even once.
Only solace for RCB is that they will face Harshal Patel from the opposite team this time . But for that RCB batters need to last beyond the powerplay.
