Marnus Labuschagne responds after Cameron Green's epic 251

Bat continued to dominate at the Gabba with Cameron Green's maiden double century followed by a productive start from Queensland's top order as Marnus Labuschagne neared a hundred.

It was another day where just three wickets fell and two of those came late in Western Australia's innings. As Queensland reached 1 for 183 at the close it was shaping as the type of match where further declarations could be needed to open up a result,

Green did not need long to take his overnight 182 to a double, having fallen for 197 earlier in the season, with consecutive boundaries off Xavier Bartlett although he later admitted there was a hint of edge involved in the shot that brought the landmark.

He continued to feast on the Queensland attack before finally picking out long-off for 251 - the seventh-highest Sheffield Shield score for a player 21 and under - which ended a fourth-wicket stand of 192 with Hilton Cartwright.

Cartwright closed in on a century for himself before lofting a catch into the deep as the declaration loomed.

Cameron Gannon broke the opening stand against his former team when Joe Burns edged to second slip but proceedings then reverted to type as Labuschagne and Bryce Street put on a stand worth 131 by the close.
