ball six and a brutal unbeaten century have set the stage for a rousing finale when the knockout matches of the Twenty20 Champions League are played over the weekend. Royal Challengers Bangalore surpassed a challenging target of 215 set by South Australian Redbacks when Arun Karthik smashed the last ball from Daniel Christian over mid-wicket in the final league match on Wednesday night. A day earlier, David Warner had cracked an unbeaten 135 off 69 balls with eight sixes and 11 fours to help New South Wales Blues knock out defending champions Chennai Super Kings from the race. Royal Challengers will clash with New South Wales in the first semi-final in Bangalore on Friday, while English county Somerset meet Mumbai Indians in Chennai a day later. The final will be played in Chennai Sunday night for the top prize of $2.5 million. The runner-up take home $1.3 million.
