Australia's senior batter Steve Smith said the last three years have been the most challenging of his illustrious career, thanks to Kookaburra changing their ball in 2020 by adding extra lacquer on a reinforced seam.
Lacquer is a plastic layer that hardens the ball while a reinforced seam makes the red cherry firmer and allows it to move around more.
However, Smith battled all these and more on way to a 33rd century on the second day of the third Test against India in Brisbane on Sunday.
It was first Test hundred in last 18 months, a very long gap for a batter of his stature.
"Since 2021 when they changed the Kookaburra ball, batting has definitely got more difficult, particularly at the same time wickets got greener as well. So it's kind of like a perfect storm coming together," Smith said at the customary press conference at the end of second day's play.
He said the challenge lies in playing out the first 30-35 overs when the ball moves around a lot and with world-class bowlers such as Jasprit Bumrah operating, the job gets even more difficult for the batters.
"I think particularly the first 35 overs, I'd say, of an innings is very challenging at the moment with the significant seam movement. But then kind of, as I said before, I think the ball stays hard.
"So if you get through that period and, you know, you've got some guys like Travis and Marshy and Alex coming in, the ball still bounces off the bat a lot harder than it used to.
"So, the last three years have probably been the hardest that I've experienced in my career. Batting-wise, in terms of the amount of movement that's been generated.
"You can see that in the way the scores have come down as well. And, you know, bowling averages come down, batting averages come down.
"And usually in the first innings of a game, if you're putting, you think back probably five years ago, you're seeing consistent 400, 500s being scored in the first innings. If you put a three in front of it these days, you're usually in a pretty strong position.
The 35-year-old
Smith said he has been feeling good in the nets. He compliment the top-order batters for negotiating the new ball that's been moving around prodigiously.
"A lot of credit has to go to the top three. They faced 50-odd balls each, which is a pretty good effort on that wicket out there. They played really well yesterday and then started, okay today.
"If we can sort of get to 30-odd overs when Travis comes in, it makes a big difference to the team. The seam probably starts to settle down around 30, 40 overs and the ball stays quite hard.
"This new ball that they changed in 2021 or whatever it is. So, you see guys batting at 5, 6, 7 that are able to hit the ball hard and get good value for their shots. That's the kind of way we've been shaping up."
