Proteas frustrate England

South Africa's lower order continued to frustrate England during the second day of the first Test at Centurion by moving on to a teatime score of 401 for eight.

After a chastening first day of this four-Test series, the tourists needed to shift star batsman Jacques Kallis early - and thanks to James Anderson, they did get their man for the addition of only eight runs to his overnight 112.

But JP Duminy (56), Mark Boucher and the determination of the tail kept England's four-man attack toiling in the sun for two more sessions.

The key wicket of Kallis came from a perfectly-pitched Anderson delivery, drawing South Africa's cornerstone into a forward push on off-stump and taking the edge when it bounced and held its line - for Paul Collingwood's third slip catch of the innings.

Graham Onions found plenty in the surface to disconcert Kallis several times this morning, but after lunch it was only the real 'effort' balls which were leaping enough to trouble the tail.

Duminy went in the hour before lunch to an action replay of Ashwell Prince's dismissal yesterday, Collingwood again the catcher at slip as Graeme Swann struck in his first over for the second day running.

Morne Morkel took a nasty blow on the side of the helmet soon after lunch before wafting a catch behind to Matt Prior off Onions.

Boucher had moved on to 49 when Swann claimed his fourth wicket, Alastair Cook taking the catch, but Paul Harris and Friedel de Wet combined well before the break.
