Deflated Siddle still dreaming

Updated: 

Peter Siddle is still dreaming of a miraculous turnaround in the first Test against South Africa in Perth.

The hosts were set 539 to win and lost four wickets on the fourth day as the Proteas took another huge stride towards victory, with Kagiso Rabada (3-49) playing a starring role.

Australia had looked in good shape when they dismissed the tourists for 242 and closed day one 105 without loss, but have been on the back foot practically ever since.

"It's probably a bit deflating to be sitting here now in the position we're in, but that's just Test-match cricket," said experienced paceman Siddle, whose side will resume on Monday with Usman Khawaja and Mitchell Marsh at the crease.

"This next partnership is going to be a big one for us. If these boys can start well and see us through for the first session, it would be nice to see where we end up.

"We're in a hard place, which is disappointing. We'll just see tomorrow, we can always dream.

"Stranger things can happen at the end of Test matches if you drag them out to late in day five."
