Rajat Patidar's blistering fifty and inspired bowling helped Royal Challengers Bengaluru record their fifth successive win with a 47-run victory over Delhi Capitals on Sunday.
Resuming on 187-9, Bengaluru bowled out Delhi for 140 in 19.1 overs at their home M Chinnaswamy Stadium after Cameron Green hit an unbeaten 24-ball 32.
RCB, who moved up to fifth, have made a late push for the play-offs but will need to win their final league match and have other results go their way to finish in the top four.
Delhi have slipped to sixth and go into their final game with 12 points. Bengaluru also has 12 points from 13 games but has a better run-rate.
Star batsman Virat Kohli took charge after hitting 27 off 13 balls to lay the foundation for Bengaluru's total in a match in which Delhi was missing skipper Rishabh Pant, who was suspended for a slow over-rate offence.
Kohli remains the leading batsman this season with 661 runs, including a century and five half-centuries.
Patidar, who made 52, soon took control in an 88-run stand with England opener Will Jacks, who made 41, before a late charge from Green.
Delhi faltered in their chase after losing David Warner for one to left-arm spinner Swapnil Singh.
Left-arm quick Yash Dayal removed Abishek Porel and Jake Fraser-McGurk in successive balls as Delhi slipped to 30-4.
Stand-in skipper Axar Patel put up a fight with a 39-ball 57, but he fell to Dayal in the 16th over and the wheels came off the chase.
Australia's Green took a wicket and ran out Tristan Stubbs to add to his batting cameo and was named man of the match for the first time this season.
