The Tigers will today get their first look at the Cricket Australia XI at Bankstown Oval, a side made up of young players who missed selection for their states for the tournament.

The youngsters have had two embarrassing losses - by 279 runs to NSW and by nine wickets to Victoria - posting totals of just 59 and 79 in those matches.

Tasmanian opener Dunk, meanwhile, is coming off 104 from 101 balls against Queensland on Monday, in a game that was also marked by impressive performances from Dom Michael (51 from 64), Tim Paine (39 from 53) and Andrew Fekete (4-30 from 9.3 overs).

"We won't be taking them lightly," Marsh said.

"We've been going through their line-up and they will definitely get better.

"They only came together a week before the tournament and you would expect them to play better throughout the tournament, so we know we will have to turn up on Saturday and play our best cricket."

Marsh said while most things went to plan against the Bulls on Monday in the nine-wicket bonus-point win, keeping the pressure on with the ball for the entire 50 overs had been a focus at training this week.

Queensland were 6-58 after 19.1 overs, before recovering to be dismissed for 196 off 48.3.

"We were happy with the way we started with the ball, and something we have been working on is the last 10 overs of the game, and they got away from us a little bit," he said.

"With the bat, a lot of things that we talked about in the pre-season happened, and to get the runs one down was exactly what we are after."

Bankstown is known to favour spin, so there is a chance Clive Rose could come in to partner Xavier Doherty in the slow bowling department.
