Bangalore: Kieron Pollard scripted Mumbai Indian's sensational four-wicket win over the Royal Challengers Bangalore with a blistering 70-run knock which overshadowed Samuel Badree's hat-trick in an IPL X match here on Friday.

Chasing a 143-run target, the Mumbai Indians looked down and out with Badree's hat-trick that reduced the visitors to 7 for four in the third over. It was the first hat-trick of this IPL season.

It soon became 33 for five, but the big-hitting West Indian and Krunal Pandya (37 not out) stitched a match-winning 93-run partnership to stage a dramatic turnaround.

The Mumbai Indians went into the innings break having the upper hand after limiting RCB to 142 for five despite Virat Kohli striking a classy 62 off 47 balls in his first competitive outing in nearly a month.

The Mumbai Indians, with the batting they possess, were expected to chase the 143-run target comfortably on a batting friendly pitch at the Chinnaswamy. However, Badree, playing his first match of the tournament, broke the visitors' back by removing Parthiv Patel, Mitchell McClenaghan and Rohit Sharma in successive balls to have the visitors reeling in the third over.

It was a remarkable effort by the West Indian spinner, considering he picked all those three wickets in the Powerplay. He dismissed Patel and Rohit with a googly, the left-hander handing a simple catch to Gayle at short extra cover while another went through Rohit's defence, sending the packed crowd into a frenzy.

The spinner had the luck on his side too as he dismissed McClenaghan off a low full-toss. He ended his spell with a wicket, sending back the in-form Nitish Rana to leave Mumbai Indians at 33 for five in eight overs. Badreee returned incredible figures of 4-1-9-4.

What followed was sensible batting from both Pollard and Krunal. They kept their team in the hunt with an odd boundary, but did not take too many risks.

The game tilted hugely in the favour of Mumbai Indians in the 16th over when Pollard pummelled Pawan Negi for two huge sixes, reducing the target to 33 off 24 balls.

Pollard departed after smashing four sixes and three fours in total, more importantly doing the job when his team needed it most.

Hardik Pandya ended the game in emphatic fashion, a six off Tymal Mills over long on.

Earlier, the RCB failed to capitalise on the good work done by Kohli, managing just 31 runs off the last five overs and lost four wickets.

Kohli, out of action for almost a month with a shoulder injury he suffered during the third Test against Australia, got into the groove in no time.

After mistiming a short ball off Harbhajan Singh for a single in the second over of the innings, Kohli found his ominous touch.

The next over, bowled by pacer Tim Southee, saw him hitting a straight six and a couple of fours, one was a crisp pull shot and another a whip over mid-on.

All this while his opening partner Chris Gayle (22 off 27) was not unable to unleash the big hits he is known for. Though the West Indian did manage to hit a six off Harbhajan, he was far from his best.

Kohli, who smashed five boundaries and two sixes, got to his half century by a dispatching a full toss off Jasprit Bumrah for a maximum.

However, the RCB lost their way after his dismissal in the 16th over, struggling to 127 for five from 110 for one in a space of 17 balls.

The opening partnership of 63 runs between Kohli and Gayle turned out to be the highest, followed by a 47-run stand between the captain and Ab de Villiers (19 off 21 balls).
