Bok lock in for Championship finale today

THE Springboks have approached their last two Rugby Championship clashes with a knockout mindset - and today's decider against Argentina at Twickenham will be no different.

With back-to-back titles on the line, the Boks are treating the London showdown as a must-win in their pursuit of southern hemisphere dominance.

By kickoff (3pm), the world champions will know exactly what they must do at Twickenham to win the tournament for a second consecutive season - a feat they've never achieved before.

Currently leading the standings by one point, the Boks can seal the title with a bonus-point victory, should New Zealand - second on 13 points - beat the Wallabies in their match in Perth.

However, just as they've approached their previous fixtures, the South Africans won't be too concerned with results beyond their control. Their focus remains firmly on staying in finals mode against the Pumas as they look to make history.
