With virtually one semifinal spot up for grabs in Group A, IPL champions Mumbai Indians will fancy their chances when they take on the bottom-placed Perth Scorchers in a do-or-die battle in their final round-robin match of the Champions League Twenty20 here on Wednesday.

Mumbai Indians are currently at the third position with six points in the points table, while Otago Volts are placed second with 10 points with two victories under their belt and an abandoned game from three ties.

Sitting at the top of Group A table with 12 points, are Rajasthan Royals, who have already made the last four stage.

The Mumbai side will have to play out of their skins tomorrow to not just earn full marks to make it 10 and come at par with Otago Volts but also finish with a good run-rate, so that if the New Zealand outfit lose their next tie there is a chance for the Indian franchise to make the cut on the basis of a better run average.

Rohit Sharma`s side got a big boost of confidence after a comfortable seven-wicket win over Highvels Lions in their previous encounter and they could not have asked for a weaker opponents than Perth Scorchers in a crucial game on Wednesday.

There is no doubt that a strong Mumbai side would do everything in their power to post a comprehensive victory against the Scorchers, if Otago lose their last league tie against Rajasthan Royals to be held in Jaipur on Tuesday night.

Even though the star-studded Mumbai outfit did not have an ideal start to the tournament as they suffered a defeat at the hands of Rajasthan Royals in the opening match before the second tie was washed out, they came back strongly to stamp their authority against the Lions.

Having restricted the Lions to a meagre 140 for 5, Mumbai reached the modest target with nine balls to spare and they would look for nothing less than a repeat of that performance where both their batsmen and bowlers fired in unison.

The bowlers, despite the absence of their match-winning pacer Lasith Malinga, did well with Mitchell Johnson, Harbhajan Singh and Pragyan Ojha successfully putting breaks to the opponents` scoring besides chipping in with important wickets.

While chasing, the batsmen did their job to perfection with Dwayne Smith hitting a 47-ball 63, and Kieron Pollard playing an unbeaten 32-run cameo towards the end; skipper Rohit Sharma, with 20 runs, also contributed to the success.

The worrying part though remains the form of Sachin Tendulkar, playing his last tournament for Mumbai Indians. But over the years he has shown that he always makes it count when it matters the most and the team will be hoping for the veteran batsman to shine on Wednesday.

Apart from him, even the likes of Dinesh Kartik and Ambati Rayudu are also yet to show their true potential in the tournament.

The favourites Mumbai have the resources to topple the lowly Scorchers, but they would certainly need to guard against over-confidence when they take the field here at the Ferozshah Kotla ground.

The Scorchers, on the other hand, with two loses and a match being abandoned are languishing at the bottom of the table with two points.

Already out of contention for a semifinal spot, the Scorchers have only pride to play for tomorrow and spoil Mumbai`s chances.

But for that they would require to strike hard with their available resources. Scorchers are here without some key players and have not been able to pose any real challenge to any of their opponents so far in the League.

After an abandoned tie against the Lions, the Scorchers lost to Otago Volts by 62 runs and then got a nine-wicket thrashing at the hands of Rajasthan Royals.

While against Otago, Hilton Cartwright was the lone batsman who showed some spark by scoring a fine 68 off 53 balls, the entire batting line-up came a cropper against Rajasthan.

After the Australian side were bundled out for a mere 120 with Adam Voges top-scoring with 27, the Royals chased down the total in just 16.3 overs. But even Voges has now flown home due to a back complaint.
