'Boult and beautiful'

Cobras were facing a massive target of 207 when their openers walked out. Their job got even tougher after an unplayable first ball from Trent Boult - it was quick, pitched up and curving away. Stiaan van Zyl looked to work the ball away towards midwicket, only for it to swerve past the outside edge and crash into the middle and off stumps. Not what van Zyl wanted on his 27th birthday. Boult enjoyed it though, as did the giantscreen operator - the message flashed, "Boult and beautiful."

Kane Williamson might have taken his time adapting to the Twenty20 format, but he has been the player of the tournament in the CLT20 so far. There were a couple of half-centuries in the qualifying stage, and he capped it off with a 49-ball hundred today. It was the quickest century in six seasons of the tournament, and he reached the milestone with a special stroke. It was a free-hit from Vernon Philander; Williamson backed away from the stumps to make room and then carved the length ball over cover for six. He was falling away towards the leg side, but such was the timing on the shot that it still cleared the rope. Doubts over his ability in Twenty20 were also cleared.

The start of Knights' innings was littered with half-chances, with mishits falling just wide of the fielders, and batsmen just making their ground when the stumps were broken by a throw. Knights had raced along to 140 for 0 in the 14th over when, at last, there was reward for Cobras. Williamson dug out a yorker from Philander towards point and set off for a quick single, Anton Devcich responded early but not early enough to beat a dead-on throw from Robin Peterson. With only one stump to aim at, Peterson lasered the ball to the base of the stumps to send back Devcich.

In the eighth over, Devcich went for a big hit over long-off. He didn't get the distance, and Hashim Amla scrambled across to his right to take a difficult low chance just within the rope. Though Amla had the ball under control, he was still sliding towards the boundary and realised he couldn't stop himself from touching the rope. He chucked the ball back into the field of play just before he hit the boundary - he might not have caused a dismissal but at least he saved four runs.
