Bangalore: When the required run rate at the start of a chase in a T20 game is a little less than eight runs an over, the task is normally easy. More so, on a Chinnaswamy Stadium pitch, known for its big scores, and against the Royal Challengers Bangalore attack. And yet the Delhi Daredevils faltered, a combination of sheer pace from IPL debutant Billy Stanlake and as many as three spinners, all of whom spin the ball away from the right-hander, doing the visitors in.
