Nathan Lyon continues to be Mr Dependable for Australia, tying down India's premier batsmen in a compelling session of Test cricket in Perth.
The offspinner's battle with Virat Kohli and Cheteshwar Pujara concluded with India 2-70 in their first innings, in reply to Australia's 326, at tea on day two.
Lyon's figures for the session - 10 overs, three maidens, 49 dot balls and 0-16 - reinforced his ability to tie down an end, giving Tim Paine the freedom to rotate quicks Mitchell Starc, Josh Hazlewood and Pat Cummins.
Arguably the only loose delivery Lyon sent down came in his final over when Kohli capitalised on the full-pitched ball and unleashed a trademark cover drive for four.
Kohli, who was unbeaten on 37 at tea on Saturday, had far greater success against Hazlewood, taking 13 runs from one of the metronomic paceman's overs.
While the pitch has been relatively tame on day two, the variable bounce on offer the previous day highlighted the key role Lyon could play later in the Test.
Having lost offspinner Ravichandran Ashwin to an abdominal strain, India face the prospect of batting last on a deteriorating pitch.
"I think the bounce that Nathan will get will be crucial on this wicket," opener Aaron Finch said.
"He talks about how much more effective he is when you do have that bounce because you can get guys caught on the crease; it brings in your bat-pad and your leg slip.
"No doubt he'll be excited by it."
Lyon also continued his much-improved batting form, compiling his fourth straight unbeaten score - a streak which includes knocks of 24 and 38 during the first Test in Adelaide.
