Trouble for South Africa! Tony de Zorzi, who'd been moving beautifully, suddenly pulls up in agony while turning for the second. He collapses clutching his right hamstring, and the physio rushes out. After a brief attempt to continue, de Zorzi simply can't carry on -- he hobbles off, retired hurt on 17 off 11.
Keshav Maharaj comes in. Harshit Rana returns to the attack. Maharaj blocks first up, then nudges towards the leg side for a single. Bosch helps the next to short fine; Arshdeep's poor throw allows him to come back for two and keep strike. Bosch then beats fine leg and slams a boundary. Short bouncer next -- Bosch takes a single. Maharaj works the last ball towards mid-on for one more. Nine runs off the over.
After 46 overs, South Africa are 341/6. They need 18 from 24 balls.
