Johannesburg: Chennai Super Kings captain Mahendra Singh Dhoni said his team was guilty of some of the worst bowling in the IPL following a seven-wicket loss to Kolkata on Monday.
Brendon McCullum smashed 81 and Brad Hodge made an unbeaten 71 as the Knight Riders successfully chased down the Super Kings' formidable total of 188 for three.
It was only the second victory for the Knight Riders in the tournament in 13 matches.

Dhoni came down heavinly on his bowlers for the defeat.
"We got the runs on the board, but our bowling was some of the worst I have seen in the IPL," Dhoni said.
"That's not to take anything away from the opposition. I thought they batted brilliantly and it's fair to say they outplayed us.
"When you are chasing a target that big you need a couple of guys to come good and the rest to bat around them. That's exactly what they did.
"It's disappointing for us especially since we had the runs on the board," he said.
The loss left the Super Kings in danger of missing out on a berth in the final four, but Dhoni said: "We have to win one more game to ensure we are in the semi-finals.
"We were in pretty much the same position in the last edition and we needed a win in the final league game to progress to the semi-finals.
"It's really up to the players. It's about what they want to achieve and how high they want to raise the bar when it's really needed.
"We are undoubtedly a good side, but hopefully the bowlers would perform better.
