For the second time in as many days, neither Joe Burns or Matthew Renshaw took their chance to cement a spot in the Australian top order for the first Test against Sri Lanka next week.

The openers were gifted two opportunities to audition against the tourists' attack as part of a Cricket Australia XI Tour Match but could only muster a paltry 43 runs between them.

Renshaw potentially emerged with more credit than his fellow Queenslander, despite being out-scored, as he at least spent longer out in the middle of Bellerive Oval.

Dismissed for seven (from 35 balls) in the first innings on Thursday, Renshaw negotiated another 29 deliveries under lights on Friday before getting out.

He actually survived a couple of early scares, before making his way to 10 from 29 balls, when the left-hander was struck on the pad by a delivery that straightened down the line and was given out leg before.

Burns opted for a more expansive approach as he attempted to improve on a first dig worth four, stroking four boundaries in an 18-ball stay.

He certainly played aggressively to race to 22, but it also proved his downfall as he flashed hard at a shortish ball where the edge flew to slips, where it was parried up by Roshen Silva at first slip and grabbed by Dhananjaya de Silva who dived across from second slip.

Burns swished his bat in disgust as the catch was taken, but still high-fived a young fan who ran over to greet him as he trudged down the tunnel.

It means both openers vying to bat alongside Marcus Harris in next week's Domain Test at the Gabba will enter the match without any strong form line to speak of, and without having made the national selectors' job any easier by punching out an irresistible case.

Burns has the weight of runs from this summer's JLT Sheffield Shield season behind him with 472 runs in 12 knocks at 47.20.

Renshaw will perhaps regret more his missed opportunities in this tour match given his paucity of runs in the Shield this summer: he has 199 at 19.90 in 10 innings, with 89 of those coming in one knock in early November.

Burns seemed intent on hitting his way into form, taking an aggressive approach from the first ball.

It nearly backfired spectacularly as he tried to pull his first delivery and got a top edge that flew over the slips cordon for a boundary.

He added two more boundaries in a much more conventional manner in his next over, again from Dushmantha Chameera, a back-foot punch that raced behind point, and a front foot flick off the pads that screamed to the mid-wicket fence.

He flicked another boundary down the leg-side to the fine leg fence, but when Chameera dropped it short outside off again, Burns slashed and that catch was taken on the rebound.

While the openers failed, Marnus Labuschagne, who had earlier taken 2-27 with his leg-spin, was assured with the bat at first drop, as he reached 33 from 62 balls when rain brought an early end to play with the Cricket Australia XI on 2-99 and 239 runs ahead.

A surprise at No.3 in the fourth Test against India, Labuschagne looks set to drop a spot to No.4 with selectors to decide between Burns and Renshaw to open alongside Marcus Harris at the Gabba, with Usman Khawaja to resume at No.3.

Labuschagne will have the chance to push on when this match resumes on Saturday afternoon, where his approach will likely be dictated by CA XI's intent to try and force a result.

First-innings centurion Kurtis Patterson continued his run-scoring spree to reach 30 from 48 balls by stumps, and again looked more comfortable at the crease than any other batter in this match.

Earlier, Labuschagne had waited 57 overs before he was asked to bowl his part-time leg-spin during Sri Lanka's first innings, and his two wickets underlined his knack for breaking partnerships.

The Queenslander's first wicket may have been a miscued short-ball caught at mid-wicket, but his second was a genuine leg-spinner's dismissal, getting dip and turn to take the outside edge of a flashing blade for Renshaw to take a sharp catch to his left at first slip.

Labuschagne could well have bagged four wickets; a tuck off the hip went just wide of leg slip, and a strong shout for leg-before was turned down in his spell of nine overs unbroken.

He finished with 2-27 as the Sri Lankans closed their first innings at 5-176 after 75 overs, following an extended middle session on this second day, as they trailed the CA XI first innings by 140.

Sri Lanka's top order all enjoyed solid hit-outs against the pink ball, but they did not look to force the pace in this three-day match, their only warm-up before meeting Australia.

While they had time in the middle, none were able to push on to record a half-century as the CA XI bowlers tied them down on the second day of their tour match in Hobart.

Dimuth Karunarate top-scored with 44 from 92 balls before he became the first wicket to fall, leg before to Scott Boland, who finished with 2-37 from 16 economical overs.

Chris Tremain collected 1-32, his wicket a nonchalant caught-and-bowled effort plucked with his left hand, and could have had a second when he had Roshen Silva edging only for it to fall narrowly short of Renshaw, who dove forward from first slip.

Boland's breakthrough came after he had switched to around the wicket with a short-leg in play, and two men out on the hook the over before drinks, peppering the Sri Lankan with short-pitched balls.

But when he went full after the break, Karunaratne found himself caught on the crease.

There was some good news for Sri Lanka earlier in the day when x-rays at a local hospital confirmed there was no break in the finger for middle-order batsman Kusal Mendis, however he did not bat in the Sri Lankans' first innings.

Mendis had copped a heavy blow to his hand while fielding at short leg on Thursday.

At the close of day two of this three-day pink ball match, the CA XI were 2-99 after Sri Lanka spent the bulk of the day compiling that slow and patient declaration at 176 from their allotted 75 overs first innings restriction agreed to by both sides pre-game.

Marnus Labuschagne and Kurtis Patterson - who cracked a superb unbeaten 157 in the first innings yesterday - resume on 33 and 30 respectively on Saturday afternoon from 2pm local time.

When their partnership is broken, the focus will fall upon uncapped Test squad batsman Will Pucovski, a candidate to replace the axed Shaun Marsh or Peter Handscomb.

Earlier, Sri Lanka resumed on 0-38 at 2pm on Friday, with no intention of challenging the CA XI's 5 declared for 316 from their 75 overs, as their top order hunkered down to adapt to the pink ball.

Fellow opener Lahiru Thirimanne made a patient 32 from 109 balls, a score matched by his captain Dinesh Chandimal.

Roshen Silva was unbeaten on 36 at the close of their innings late on Friday evening.

Now Sri Lanka plan to bat again under lights during Saturday's final day after the CA XI conclude their second innings.
