Queensland have recorded the record run chase by any team at Blundstone Arena to defeat Tasmania by four wickets in Round 6 of the JLT Sheffield Shield..

The Bulls were 8/86 at stumps on Day 1 before conceding a 413-run lead to the Tigers on second innings, but swung the game back dramatically in the remaining day and a half.

Full scorecard

Riley Meredith was the pick of the Tigers bowlers in the Bulls' second dig, snaring 3/70 from 27 overs.

The hosts had their chances in the final session to give themselves a greater shot at maximum points but some catching opportunities were grassed once the new ball was taken.

Despite the loss, other results mean the Tigers are within touching distance of second place and a spot in the final when the competition resumes after the Big Bash on February 23 in Adelaide.

Adam Griffith said after play that they knew the day would pose a tough fight.

"The wicket was getting better and better to bat on and we probably didn't take our opportunities," he said.

He continued to say that the Tigers played two and half days of really good cricket before the reigning Shield champions came back into the contest.

"I think we left another 60, 70 or 80 runs out there in our second dig, so that was disappointing. Then last night with the ball we didn't start the way we wanted to."

"Today, we toiled really hard and there were some really good performances. I thought Riley Meredith bowled really well this game."

"But like I said, when you miss those opportunities and you're not getting many in these conditions, it's pretty disappointing."

Griffith then reviewed how their first six matches of the Shield have gone.

"I think this game probably sums up our red ball season," he said.

"We played some really good cricket and created opportunities but when the moment was there to win the game we couldn't quite grasp it."

"But there have some really good performances throughout the season so far that will take into the Big Bash."

Bulls fight their way back after Bailey ton

A 24th First-Class century for George Bailey and a 10th Sheffield Shield half-century for Simon Milenko pushed the Tigers' second innings lead to 414 on Day 3 at Blundstone Arena, before the Bulls' top order rescued their dire position.

Day 4 has potential to be another thriller with Queensland requiring a further 250 runs and the Tigers needing eight more wickets.

The hosts would've found themselves slightly more up against it had Riley Meredith not knocked over Joe Burns (74) on the third to last ball of the day.

Instead, the pressure is on Marnus Labuschagne (58*) to be the visitors' anchor on the final day with Charlie Hemphrey fresh at the crease.

Milenko is backing himself, and the Tigers' four front line quicks to re-find their first innings form.

"We probably didn't execute as well as we would've liked," he said.

"But the brighter side is we still have a 250-run lead and we're already keen to make amends for straying slightly this afternoon."

The all-rounder, who featured in a 77-run stand with Alex Pyecroft earlier in the day, continued to say there's still a bit in the deck.

"This pitch is a fair bit flatter than the previous two (vs. Victoria & South Australia)," he said.

"But we got the ball to reverse a little late today so we know we've got a bit to work with in the morning as the pitch becomes more abrasive."

Bailey's 96* powers Tigers

An unbroken partnership of 104 between George Bailey (96*) and Matthew Wade (40*) has powered the Tigers to a strong position at stumps on Day 2.

After Jackson Bird (3/40) wrapped up the Bulls' first innings inside the opening half hour this morning, Tasmania made the visitors pay to build a lead of 300 by stumps - with six wickets in hand and two days to play.

Jordan Silk (54) and Jake Doran (26) earlier provided a solid foundation as the deck began to flatten out.

Silk, who now sits sixth in the Shield's run-scorers this season, says the aim is to bat for another long period tomorrow.

"To have a lead of 300 at this stage is pretty great, obviously, but with so much time left still our plans haven't changed too much," he said.

"They've just taken the new ball so we'll look to get through that early tomorrow before attempting to do what we did late today."

Silk agreed that his Tigers teammates were willing Bailey to his ton before stumps up in the viewing area.

"We're really pleased for him. He's worked hard all season," he said

"It was just a matter of time before he got some rewards. Hopefully, he can get those four more runs and kick on."

Pyecroft spell lifts Tigers

A maiden five-wicket First-Class haul for Alex Pyecroft - in just his second Sheffield Shield match, has pushed the Tigers into a strong position after Day 1.

Looking comfortable at 1/41 in pursuit of the Tigers first innings of 167, Pyecroft's spell triggered a remarkable collapse. The Bulls 8/86 at the close of play.

Each of the Tigers remaining fast bowling cartel - Jackson Bird, Gabe Bell & Riley Meredith, also have one wicket each.

Earlier in the day, the Tigers were in trouble at 4/21 inside the first session after the Bulls got the ball talking early on a pitch which was seaming regularly.

A steadying partnership between Matthew Wade and George Bailey got the hosts to 60 with no further loss at lunch before the Tigers added a further 107 before being all out.

A 10th wicket partnership of 37 between Bell and Meredith could prove key when this game goes deeper.

"I was a little bit disappointed with the way we batted," said Matthew Wade after play.

"I then thought our first eight or nine overs were a little disappointing in our response with the ball."

"But then Pikie got us going with a few wickets. The last hour and a half was as good as we've bowled all year."

"We didn't have a great day for six hours, but we found a way to get it done."

He then touched on his own 63, his sixth half-century of the Shield summer which takes him atop the Shield standings.

"I think this wicket does a bit if you try and drive a bit too early, so it's about giving yourself the best chance."

"I would've like a few more, I think I probably left 20 out there but it was nice to get amongst the runs."

Pyecroft's quick adaptation to Shield cricket from Premier Cricket at North Hobart isn't a surprise for Wade.

"I said during last game that the length he bowls here was going to suit perfectly," he said.

"He got the ball up there and gave it the chance to move sideways and got the rewards today."

The Tigers will be looking to drive home their advantage early tomorrow before posting a big second innings lead.
