Jacques Kallis and Robin Uthappa each scored unbeaten half-centuries to steer the Bangalore Royal Challengers to a thumping nine-wicket win over the Mumbai Indians in the Indian Premier League on Sunday.

Man-of-the-match Kallis hit 69 and Uthappa added 66 to guide Bangalore home with 11 balls to spare at the Wanderers. Kallis blasted five boundaries and two sixes in 59 balls while Uthappa faced 42 balls and smashed eight boundaries and two sixes to help Bangalore to 150-1.

Bangalore were set on course by its South African medium-pace bowler Dillon du Preez, who bagged 3-32 from his four overs and bowled one maiden. He removed Sachin Tendulkar (11) and Ajinkya Rahane (0) in successive balls, and then accounted for JP Duminy on one.

But twin half centuries from Dwayne Bravo and Sanath Jayasuriya nullified a fine bowling performance from Royal Challengers Bangalore and helped Mumbai Indians post 149 for four.

In reply, Bangalore lost their only wicket when opener Wasim Jaffer was easily caught by Abhishek Nayar at square leg off Zaheer Khan in the third over.

But Kallis and Uthappa batted with real conviction, Kallis using his experience to dominate the Mumbai attack. The veteran South African batsman started off aggressively, putting away to the boundary anything short and outside off stump.

Earlier, debutant Preez's three-wicket burst and a fine performance on the field by the Royal Challengers were undone by opener Jayasuriya's 52 off 43 balls and the late blitzkrieg of 66-run partnership for the fifth-wicket between Bravo (50 off 40 balls) and Nayar (29 from 20).

South African Preez (3/32) sent the Mumbai Indians top-order packing, picking up three quick wickets.

The 27-year-old right-arm fast medium bowler first accounted for the dangerous Sachin Tendulkar, who was looking to cut loose with a couple of sweetly timed boundaries.

The Mumbai Indians skipper chased a widish delivery and the thick edge flew to Rahul Dravid at slip, who didn't make any mistake.

Dravid, who returned to the side after the birth of his second child, was given catching practice the very next ball when Ajinkya Rahane guided Preez's outgoing delivery to the slip.

With Preez gunning for a hat-trick, JP Duminy survived a leg before appeal but perished in the South African's very next over.

Left-handed Duminy went for a mighty heave but the ball kissed the inside edge of the bat and Mark Boucher took a low catch behind stumps.

While Preez was rocking Mumbai, Jacques Kallis and Praveen Kumar did their job to keep the opponents in shackles with a tight line and length.

It was left to Jayasuriya to give Mumbai some freedom. He decided to launch into Preez, hitting him for a boundary and six off successive deliveries.

It was the 39-year-old Jayasuriya's lusty hitting that gradually helped Mumbai Indians find their feet.

He, along with Dwayne Bravo, accelerated the innings with a 53-ball 60 in which the bulk of the scoring was done by the Sri Lankan.

However, Jayasuriya fell trying to step on the gas. The Sri Lankan tried to hit RE van der Merwe's first ball over the ropes only to hole out at square leg. His 43-ball 52 contained six boundaries and a six.

Nayar then stepped in and with Bravo put on 66 runs in 34 balls for the fifth wicket.

West Indian Bravo's 40-ball 50 was studded with one four and two sixes while Nayar hit four boundaries in his 29 that came off 20 balls.

Together, they helped Mumbai Indians score close to 100 runs in the last 10 overs after the team was 53 for three at the half-way mark.
