It seemed a pitch conducive to bad batting. It really didn't look like there was much to stop the batsmen, it's just that they didn't score. Perth badly wasted the opening stanza; on the weight of the rest of their innings, they probably should have made 175. The spinners had Marsh struggling to pick the gaps and pretty much everyone could have kept Collingwood bottled up if it weren't for his arsey paddling.
Beer did a lot of damage for Perth across the tournament by taking the new ball and sliding the ball on at opening batsmen who apparently expected him to turn one. It was a big play, perhaps the most crucial, for the Sixers to find someone who could actually play him for what he is, but I still can't believe it was Henriques.
