Johannesburg: Early birds into the semifinals' nest - South Australia Redbacks - will take field on Tuesday with an intent to decimate a hapless Guyana outfit and send intimidating signals to their opponents in the last-four stage.The Caribbean champions - who are already halfway through packing their bags - will fly back home after their last league encounter but would love to do that on a winning note. Considering what Guyana has done until now, placing bets on that may leave one with a sheepish grin in the end.If anything, only Guyana's batting has shown signs of improvement. But their school-boy fielding and catching has undone whatever decent totals skipper Ramnaresh Sarwan & Co. - none of whom has scored a half century yet - notched up in the last two games. Their bowlers, too, have failed to keep rival batsmen in check, with only Devendra Bishoo having a notable performance of three wickets against the Mumbai Indians.The Redbacks, on the other hand, have won everything under a leader â Michael Klinger â who has led from the front despite having minuscule T20 experience. Flying starts have been the norm of Redbacks' innings whether they chase or set targets.Led by pace machine Shaun Tait, the bowling department has been well looked after by Daniel Christian who sent the Royal Challengers Bangalore packing with his four-wicket haul.Like most Aussie outfits, the South Australians have been swift in the field, pouncing on the ball and putting doubts in the minds of men running between the wickets. That, in fact, has made their score look like 15-20 runs more than the actual one. The game against Guyana gives the Redbacks a chance to rest the overworked staff and test those warming the bench until now. But whatever the combination Klinger may field, he would not want the winning streak to break and hit a speed-breaker ahead of the knock-out stage.
