AB was batting on a different pitch to everyone else but the key was actually a ball change the Aussies got because the first one went out of shape. That replacement ball talked.
Starc was phenomenal in that spell but credit to two other players as well:
Lyon - He is unplayable against lefties these days, they just can’t do anything against him. Yes, they hit some boundaries but he is just relentless. Picking up Elgar and Amla in his first over set that rout up. He is such an important cog in this side now.
MMarsh - He was the equivalent of AB in the Aussie innings. That pitch has plenty of life and he played the conditions perfectly. Yes, he gave some chance but they were half chances at best, he knew those chances would come unless you are ABD or Smith and on a different level to everyone else out there. He controlled that innings so well. Saw off the first evening, then the new ball and then let Starc do his thing while he was going, then went up a few gears when Starc departed. That could well be his career starting innings, it was pure class.
