NATHAN Lyon approaches his home Test in Adelaide under no illusions about South Africa's intentions to take him down.
The off-spinner's first spell as Australia pushed for an unlikely fifth-day win at the Gabba lasted two overs and cost 26 runs as Jacques Kallis and Hashim Amla enacted their plans to hit him out of the attack.

Gabba Test Day 5
Summary of the final day's play in the drawn first Test between Australia and South Africa at the Gabba.
Amla skipped down the track and hit his fifth ball for six over long on, while Kallis smashed two fours and a six off his next over. The final blow was so flat and straight it almost decapitated umpire Billy Bowden.
Lyon recovered to pick up the wickets of Kallis and Jacques Rudolph, and could not contain his excitement.
He has endured a modest start to the season with 10 first-class wickets at 58, and was always going to play a support role in Brisbane, but more will be expected of him in the second Test at the Adelaide Oval.
If Mitchell Starc comes into the XI, Lyon will benefit from the rough created by the left-arm paceman.
South Africa will revert to normal proceedings, and recall leg-spinner Imran Tahir.
The immediate future of Australian batsman Rob Quiney, who was out hooking for nine on debut at the Gabba, depends on the fitness of Shane Watson.
Meanwhile, South African great Barry Richards wants to see popping creases widened to prevent the torrent of no-ball reviews being a blight on cricket.
Three times in the first Test at the Gabba - with Australia suffering twice and South Africa once - a wicket was denied by the third umpire's technology after the bowler marginally overstepped with his front foot.
The biggest drama of the final day came when Hashim Amla, on 7, played on a full James Pattinson delivery as the tourists were battling against the new-ball at 1-26.
Pattinson over-strode by a mere centimetre, with his heel landing on the popping crease, but the third umpire made the correct call to let Amla stay. Fellow Australian paceman Peter Siddle was denied in the same manner against Jacques Kallis on day one while Proteas quick Morne Morkel was the victim of a dubious call when Ed Cowan gloved down the leg-side late on day three.
''If you want to fix it you could go back to the back-foot rule but I don't think that's going to happen, so why don't you widen the line?'' Richards said on ABC Radio. ''It would help the umpire and the bowler.''
Elsewhere, Justin Langer is expected to be announced on Wednesday as the new head coach of Western Australia. The former Test opener will relinquish his position as Australia's batting coach for the appointment with the Warriors, who are in disarray following the Champions League T20 misbehaviour saga and the resignations of captain Marcus North and coach Lachlan Stevens.
Langer will be replaced for the remainder of the international summer by Stuart Law.
