Hyderabad: Kolkata Knight Riders suffered a dramatic batting collapse after a strong start as they scored 121 for six against Auckland Aces in their Champions Trophy Twenty20 qualifiers opening match on Monday.

Electing to bat, KKR made a breezy start with Jacques Kallis (33) and Manvinder Bisla (45) raising 73 runs for the opening stand before their side slumped to 106 for six in the 18th over at Rajiv Gandhi International Stadium.

KKR lost five wickets in eight overs for the addition of 33 runs, with Kyle Mills taking two wickets -- of Kallis and Manoj Tiwari (1) -- in the space of four balls in 15th over.

Just an over earlier, Yusuf Pathan's struggle at the crease ended as he was cleanbowled by Andre Adams for just 12.

Ryan ten Doeschate was run out for three in 16th over and Shakib Al-Hasan (4) met with the same fate two overs later.

Earlier, Kallis and Bisla made a strong start and raised hopes for a big total.

Bisla showed his aggressive intent by hitting three fours off Chris Martin as he took 13 runs from the second over. He then smote Mills for a six in the next.

Kallis joined in with two fours off Adams in the sixth over as KKR scored at a brisk pace with at least a boundary every over and run rate at eight.

Bisla, however, fell in the 10th over while trying to work a full toss off Michael Bates from off stump to the leg side only to get a leading edge that lands at the hands of Guptill at the cover region. His 32-ball 45 had seven fours and one six.

Kallis was out in the 16th over with a bit drama involved. He hoicked Mills off the pads and it seemed set for six. Robert Quiney, who was prowling in the deep, ran back and tumbled to the right to take a catch, a few feet in front of the ropes.

Kallis can't believe it though he was on his way to pavillion after asking the fielder whether it was a clean catch or not. His 33 came from 35 balls and studded with four fours.
