Renshaw was widely viewed as a nurdler following his test debut at Adelaide Oval, but in India has looked to attack some of the world's best bowlers.
He dispatched poor balls with ease yesterday, stroking six well-timed boundaries to race to 24 off 22 balls. The comparisons with Matthew Hayden will continue to flow thick and fast.
"The essence of a good test player is absorbing pressure," Hayden said on Star Sports.
"The greatest batsmen have to do that, they have to see the conditions and outlast bowlers. It's a battle of attrition."
Renshaw played with soft hands, waiting for the ball to come to him on the slow- and-low surface. The Middlesbrough-born batsman put the fast outfield to good use, cover driving paceman and spinners alike.
Coach Darren Lehmann was full of praise for Renshaw's resilience in the first test, when he was struck on the forearm and battled a stomach bug.
"When he gets out in the middle, he knows exactly what he wants to do and how he wants to do it," Lehmann said.
"For a 20-year-old that's pretty special.
"That's good for a young man to have that insight into the game so early."
Australia went to lunch on 109 for three with skipper Steve Smith on 34 not out.
