De Kock, playing in just his third game of the season, blasted nine fours and three sixes during a 39-ball 69 at M. Chinnaswamy Stadium on Sunday afternoon.
The Daredevils compiled 187-6 but the rain teemed down one over and one ball into Bangalore???s reply ensuring the sides collected a point each, a result that sealed the hosts??? spot in the play-offs but left them??all-but certain??to figure in the elimination qualifier.
Delhi openers De Kock and Shreyas Iyer (20 from 18) batted with intent after being put in by Bangalore, securing their fifty partnership in the sixth over prior to 20-year-old Iyer picking out Chris Gayle at backward point.
De Kock continued to motor alongside JP Duminy (67no from 43), bringing up his half century off 30 balls during a 55-run stand with his fellow South African, but the left-hander???s exit in the 12th over saw seventh-placed Delhi lose four wickets for 31 runs in four overs.
Duminy, however, finished with a flourish, smoking his fourth half-century of the campaign and helping ensure Bangalore???s star bowler, Mitchell Starc, went wicketless for the first time this term.
Rain had been forecast, however, and it came – and failed to entirely clear up – after home openers Gayle (1no) and Virat Kohli (1no) had nudged their team to 2-0 from seven balls, with the game called off shortly after 3pm.
Bangalore, who would have needed an extremely heavy defeat to Delhi to miss out on a play-off berth, are up to the second in the standings but??will probably??be pushed down to third after Sunday evening???s Sunrisers-Mumbai match.
