The clash between the two most impressive teams of the IPL proved to be a one-sided affair as Kolkata Knight Riders cruised to a six-wicket victory.
They displaced the Delhi Daredevils from the top spot they had held virtually from the start of the tournament.
Jacques Kallis made two big early breakthroughs, Sunil Narine continued to confound batsmen and Rajat Bhatia quietly continued to prove an important part in Knight Riders' bowling as they stifled Daredevils' formidable batting.
The chase of 154 proved straightforward, the only real moment of concern for Knight Riders coming when Brendon McCullum brutally pulled a delivery straight at their dug-out in the 15th over.
Daredevils' two most productive batsmen this season have been Virender Sehwag and Kevin Pietersen, and their consistency had so far shielded the rest of the team's batting from too much scrutiny.
With Sehwag finally failing after a record five half-centuries in a row and Pietersen back home, the rest of the line-up couldn't quite deliver.
