DHAKA, Bangladesh (AP) - South Africa captain Graeme Smith scored an unbeaten half century to lead his team to the brink of victory on day three of the first test against Bangladesh.

Chasing a target of 205 for victory after bowling out Bangladesh for 182 in its second innings, South Africa was 99-1 at tea, with Smith on 50 and Hashim Amla not out 21.

Smith brought up his 50 from 80 balls, with five boundaries to continue South Africa's strong day three performance, in which Jacques Kallis completed a five-wicket haul and Mark Boucher re-claimed the world record for wicketkeeper dismissals.

Neil McKenzie (26) was the only South Africa batsman out, miscuing a pull shot to Habibul Bashar at square leg, off a delivery by Shahadat Hossain.

Earlier in the day, South Africa all rounder Kallis skittled Bangladesh's lower order and ensure his team chased an achievable total.

Kallis took 5-30 as Bangladesh lost its final five wickets for 34 runs.

Starting with an overnight score of 125-4, Bangladesh added a further 23 runs before the introduction of Kallis to the attack brought dividends in his first over as he removed opener Junaid Siddique (74), caught behind by Boucher.

From then on, the wickets fell at regular intervals. Fellow South African Dale Steyn next trapped Aftab Ahmed (24) lbw in the first ball of the next over, with the Bangladesh batsman choosing not to play a shot to a delivery that cut back into him.

Batsman Mushfiqur Rahim (2) was caught behind down the leg side by Boucher off a Kallis delivery, to complete the loss of three wickets for three runs.

An inspired Kallis next clean bowled Mohammad Rafique (14), had Mashrafe bin Mortaza (11) caught at slip, and closed out the innings by having Shakib Al Hasan (3) caught behind.

Boucher's four catches moved him back into the lead for wicketkeeper dismissals with 417, one ahead of just-retired Australian keeper Adam Gilchrist.
