Chennai Super Kings, languishing at the bottom of the league ladder, all but knocked defending champions Kolkata Knight Riders out of IPL-18 with a two-wicket victory at the Eden Gardens on Wednesday. The Knights, their Playoff hopes hanging by a thread, have now walked into a complex mathematical improbability. 

The visitors, chasing a target of 180 and with five wickets down, looked headed for defeat before Dewald Brevis ignited hopes by clobbering Vaibhav Arora for 30 runs in the 11th over. When the South African fell in the very next over, CSK had to fight again, but skipper MS Dhoni guided the youngsters at the other end as the yellow brigade crossed the line with a couple of deliveries to spare.
