Brown/Reuters  Steven Finn struck a key blow in England's bid to
stay on top of the world Test rankings when he inflicted more
Lord's misery on Jacques Kallis at the end of a compelling day's
cricket.  Kallis and Hashim Amla's third-wicket partnership of
81 was threatening to bat England out of the match and deny them
any chance of the win they need to square the three-match series
and prevent South Africa displacing them as the world's top Test
team. Amla had offered a difficult chance down the leg side to
Matt Prior early in his innings.  But with less than 20 minutes
remaining, Finn nipped one back at Kallis and won an lbw
decision from the umpire Simon Taufel.
