Test snub a weight off my mind: Bancroft

When overlooked by Australia's Test selectors, opening batsman Cameron Bancroft felt a weight lift from his shoulders.

No more worry. No more speculation. No more people talking about his prospects of a Baggy Green cap.

"It was impossible to not think about it ... it was always around," Bancroft said on Sunday.

"To be perfectly honest, finding out that I wasn't going to be in the squad, if anything, just a weight lifted of your shoulders - you don't have to worry about anything now, you have just got to go out and score runs."

So go out and score runs he did: 111 of them for Western Australia against South Australia on Sunday in their Sheffield Shield match in Adelaide.

Bancroft's ton set up a final-day run chase for the West End Redbacks; needing 316 to win, they'll resume on Monday 0-17.

The 22-year-old Bancroft was the mainstay of the Alcohol.Think Again Western Warriors' second innings, compiling his fifth first-class century.

In partnership with Shaun Marsh, who made 92, Bancroft steered WA to a powerful 2-217 before the visitors lost their last eight wickets for 78 runs to give SA a sniff of victory.

His 258-ball knock ended when run out but was a perfect response to Australian chairman of selectors Rod Marsh's reason for overlooking him: that he was "a few hundreds" shy of earning a Test spot.

"That was the decision that they went with. I can't do anything about that," Bancroft said.

"And certainly for me, scoring big runs and striving for consistency, that is any player's dream and goal. That is what I take away from that message from Rod.

"And hopefully I can keep making some big hundreds and big scores and you certainly put pressure on other people but also put your state in a good situation and winning games of cricket, which is what it's all about."

Bancroft was included in Australia's Test squad for a tour of Bangladesh last month that was postponed for security reasons.

"It was disappointing, especially being my first tour," he said.

"The right decision was made in the end obviously for safety reasons but it was very disappointing.

"But things happen for a reason and I have just got to keep doing what I'm doing and keep scoring hundreds and making big runs and give yourself a chance."
