Queensland Bulls star Chris Lynn was at his power-hitting best today in Queensland grade cricket, smashing 19 sixes in a double-century to send a warning for the forthcoming Matador Cup competition.

Lynn is expected to be a key performer for the Bulls at next month's Matador One Day Cup and a potential Queensland captaincy candidate if Usman Khawaja is as expected called up to national duties.

The right-hander hit 209 from just 137 balls for Toombul against a Norths attack containing Queensland teammate James Hopes, former-Test spinner Nathan Hauritz and former Bulls paceman Matthew Gale.

Lynn peppered the surrounding streets and rail line at Toombul's home ground of Ken Mackay Oval with 19 sixes and 12 fours, as he and former West Indian and ex-Queensland batsman Brendan Nash (123no from 84 balls) helped the home side to a massive score of 3-385 from their 50 overs.

Lynn took 34 off one over by former Queensland Under-19 paceman Barry Bester including five sixes, with his fourth ball boundary shot landing just short of the rope to miss out on a rare over of sixes.

The Australian T20 representative came to wicket at 1-13 and batted until the final over of the innings.

"I was really pleased with the control I had to bat for the length of time I did," Lynn said after play.

"We were a bit behind where we wanted to be with the run-rate until the last 20 overs but we got going.

"It was like we tacked a T20 innings on at the end to get a decent score."

With Queensland teammates Khawaja and Joe Burns tipped to be named in the Test squad to tour Bangladesh next month, Lynn will be a vital performer for the Bulls as they chase a limited overs title in the domestic one-day tournament in Sydney at the same time.

Queensland will name its squad next week for the tournament.
