Inspired pace bowling from Alzarri Joseph in a lively half-hour before the close enabled West Indies to creep back into the first Test against South Africa on Wednesday.After their batting collapsed to skillful, if not palpably menacing fast bowling from Anrich Nortje, the Caribbean side defied an explosive start from opener Aiden Markram and reduced the South Africans to 49 for four in their second innings at the close on the second day at SuperSport Park.Joseph has so far taken two for 17 from four overs to follow up his maiden Test five-wicket haul and Kemar Roach and Jason Holder each grabbed a wicket, as West Indies strongly finished a day on which 16 wickets fell – all to the pacemen.The visitors will have their work cut out on Thursday trying to stop the Proteas from building on their current lead of 179, with first innings century-maker Markram unbeaten on 35 that already includes six boundaries.“We know that we have been in this situation already a few times, so we know what we have to do, and we have the confidence in our bowlers to go out there and get the job done,” West Indies vice-captain Jermaine Blackwood said in a TV interview after play.“As batsmen, we did not go out there and put the runs on the board that we wanted, but we still have a second innings, and once we can go out there and get the ball in the right areas, I think we can have a bat again (on Thursday).”
