An ugly confrontation between Jacques Kallis and Kemar Roach overshadowed a convincing seven-wicket victory for South Africa in the third and final Test against West Indies Tuesday. Chasing 47 for victory, the South Africans reached their target about 25 minutes before lunch on the fourth day at Kensington Oval, when AB de Villiers cut a short ball outside the off-stump from Roach through backward point for four. The result meant that South Africa wrapped up a 2-0 series victory, after it also won the first Test inside four days by 163 runs at Queen's Park Oval in Trinidad, and the second Test was drawn at Warner Park in St. Kitts. But drama unfolded between Kallis and Roach before the match came to a conclusion. Kallis was nearly decapitated, when a searing bouncer from Roach almost removed his helmet, and a long-distance, verbal exchanged erupted between the two players. It took the intervention of Shivnarine Chanderpaul to pull Roach away, and a few more West Indian players got involved to cool tempers. Next delivery, the final of the over, Kallis received another bouncer from Roach that sailed over his head, and the two glared at each other. Kallis then walked past Roach to have a mid-pitch conference with Hashim Amla, and the confrontation heightened with arm-waving, and shouting, prompting Australian umpires Steve Davis and Simon Taufel to intervene. Things settled down after Davis and Taufel had a long chat with West Indies captain Chris Gayle. It was a strange turn of events for Roach. He bowled with pace and hostility to snare all three South African scalps that fell before the visitors completed victory. Roach had Graeme Smith caught at mid-wicket for 10 after he had also struck him on the helmet, bowled Alviro Petersen off the inside edge for six, and had Amla caught at gully for the top score of 25 with two runs needed. Aterwards, Kallis had to pursue Roach to shake his hand in the statutory end-of-the-game appreciation, and even then the two still seemed to carry on the fuming, with de Villiers this time stepping in to part them, and receiving an earful from the fast bowler. Earlier, Morne Morkel too, wrapped up the West Indies innings in the first hour, when he ended with three for 33 from 14.1 overs. Morkel bowled Sulieman Benn for nine, had Roach caught behind for eight, and Brandon Bess caught at second slip for a first-ball duck, leaving Shivnarine Chanderpaul unbeaten on 71. Johan Botha was named Man of the Match for his match figures of seven for 102, and Dale Steyn was named Man of the Series for his 15 wickets at 18.13 runs apiece. Steyn, meanwhile, is to be investigated by match referee Jeff Crowe for allegedly spitting in the direction of West Indies spinner Benn. The alleged incident took place as Steyn walked off after he had been dismissed in the morning session Monday. – Agencies Scoreboard West Indies (1st Innings) 231 South Africa (1st Innings) 346 West Indies (2nd Innings) Gayle c Boucher b Steyn 10 Richards c Petersen b Steyn 17 Deonarine c Prince b Steyn 00 Chanderpaul not out 71 Nash c Kallis b Botha 12 Bravo b Harris 02 Ramdin c wkpr Boucher b Botha 01 Shillingford lbw b Botha 25 Benn b Morkel 09 Roach c wkpr Boucher b Morkel 08 Bess c Kallis b Morkel 00 Extras (b1, lb1, w1, nb3) 06 Total (all out, 65.1 overs) 161 Falls: 1-27 (Richards), 2-27 (Deonarine), 3-36 (Gayle), 4-70 (Nash), 5-74 (DJ Bravo), 6-75 (Ramdin), 7-128 (Shillingford), 8-151 (Benn), 9-161 (Roach).
