London, August 24: Steve Waugh and younger twin Mark became only the second set of brothers in Ashes history to make hundreds in the same innings as Australia declared on a huge score of 641 for four on the second day of the fifth and final Ashes Test here at The Oval on Friday.

At the close England were 80 for one, still 362 runs short of avoiding the follow on, and Australia on course for a victory that would give them the five match series 4-1.

Marcus Trescothick was 55 not out and Mark Butcher 10 not out.

England opener Michael Atherton, in what could be his last Test, was the man out. On 13, he was bowled by a sharly-spinning Shane Warne leg-break, England 58 for one in the 13th over - clearly unlucky for some.

Australia captain Steve Waugh finished on 157 not out, over five hours of relentless run scoring seeing him face 256 balls including one six and 21 fours. Damien Martyn was 64 not out after Mark Waugh had made 120.

Only Ian (118) and Greg Chappell (113), also at The Oval back in 1972, had ever achieved the same brotherly feat in 124 years of Anglo-Australian Test cricket.

Steve Waugh's innings was especially impressive as he showed no ill effects from the double tear of his left calf muscle that had kept him out of action since the third Test at Trent Bridge.

His fortitude was in marked contrast to a number of England cricketers out for longer with seemingly lesser injury problems.

On a perfect day for batting it was younger brother Mark who was first to three figures as England's attack wilted in the sun.

Waugh junior, 92 not out at tea, brought up his 20th Test century and sixth against England with a single to third man off Andrew Caddick. He had faced 161 balls in an innings of nearly four hours duration, and hit one six and 13 fours.

As if bored by the bowling, he then proceeded to play some extravagant shots. But giving himself room against Darren Gough, he was bowled for 120 and Australia were 489 for three. He and his brother had put on 197 in good time off 307 balls.

There was no such cavalier approach from Steve. He spent 28 balls getting from 98 to 100, nearly an hour in the 90s as a whole, before the vital run was scrambled off Gough, Waugh diving into the crease.

Even flat out on the ground he still managed to raise his bat. His 27th Test century, his 10th as captain and ninth against England had come off 190 balls including one six and 15 fours.

Only cricket legend Don Bradman, with 19 hundreds, had made more centuries for Australia against England.

It might all have been different for England had they taken a chance in the first over of the day but yet again in this series a dropped catch cost them dear.

Caddick took the new ball and with the fourth delivery of the day, found the edge of Mark Waugh's bat

But Butcher at second slip dropped the routine chance with Waugh on 50.

The Surrey batsman, England's match-winning hero with 173 not out at Headingley, was now very much the villain.

He would not have been popular with England's four main bowlers, all of whom had conceded over 100 runs, 174 taken off 39 Phil Tufnell overs alone.
