Cricket Australia has stressed their early-season pink ball trial won’t end under-pressure opener Chris Rogers’ Test career.

The colour-blind Rogers has withdrawn from Victoria’s day-night Sheffield Shield clash against Tasmania, starting on Friday afternoon, due to his difficulties in sighting the pink ball.

Coming off a disappointing series against Pakistan, the 37-year-old’s position is under threat and his four-day absence won’t help in holding off top-order challenges from Phil Hughes and Shane Watson.

But CA team performance manager Pat Howard insists the left-hander’s withdrawal won’t be a major factor in selection for the first Test against India, starting December 5 in Brisbane.

“The selectors have reiterated that no player is judged on one match,” Howard said.

“The four-man selection panel rate players on their consistency over a period of time and particularly their ability to perform in pressure situations.”

Rogers – who averages 36.06 in 16 Tests, and 33.25 this year – has also denied his rest should affect his selection chances, especially following a big season of English county cricket for Middlesex.

“I’ve played more first-class cricket than just about anyone in the world this year, so I don’t think sitting out one match for Victoria will affect me too much,” he said.

CA has pushed ahead with pink ball trials as they aim to stage a proposed day-night Test match against New Zealand in Adelaide next summer.

But Victorian coach Greg Shipperd has argued CA should have waited until later in the season to unleash what they view as an improved pink ball in Shield cricket.

The new Kookaburra ball, which has green stitching on the seam instead of white, also appears quite different to the pink Duke that Rogers faced in Abu Dhabi four years ago.

Rogers, who had lodged his concerns with a sympathetic Howard, would only have had one training session facing the new ball.

He understood the trials were being conducted for the future of Test cricket and acknowledged it was important to make the ball more visible.

“I just haven’t had the opportunity to practice with (the new Kookaburra ball) because I’ve been playing so much,” he said.

“Given my last experience with day-night first-class cricket four years ago had its challenges for me, there are still a lot of unknowns and doubt about it from my perspective, so I’ve decided to sit this one out.”
