Queensland 3 for 227 (Burns 65*, Renshaw 52*, Heazlett 51) beat South Australia 226 (Cooper 62, Stanlake 3-38, Kuhnemann 3-39) by seven wickets
The pair capitalised on the foundation laid by opener Sam Heazlett, who carved out another blistering half-century, to mow down South Australia's sub-par total of 226 in 35.5 overs to secure a second straight win to start the season.
The Redbacks were earlier humbled by the bowling combination of Billy Stanlake and Matthew Kuhnemann. Stanlanke produced another hostile spell to claim 3 for 38 from his 10 overs while Kuhnemann, with his left-arm orthodox, took the prize wicket of Alex Carey and ripped through the tail to finish with 3 for 39.
Queensland won the toss and sent their opposition in knowing the tacky nature of the surface with the early morning start would make scoring difficult. South Australia started solidly but were never able to get away.
Stanlake was again held back until after the powerplay and his impact was enormous as he found Jake Lehmann's outside edge with extra pace and bounce. Renshaw then made the surprise breakthrough with his offspin removing Jake Weatherald for 44 before Kuhnemann clean bowled Carey as he tried to slog sweep to midwicket.
Tom Cooper played superbly for 62 but he watched carnage unfold at the other end as Stanlake and Kuhnemann took 4 for 9 in 18 balls as South Australia were about to launch with 10 overs to go, and they folded meekly for 226.
Max Bryant got the chase off to a flyer clubbing six boundaries in 21 balls before he flicked one straight to short fine leg and Queensland briefly threatened to be derailed when Marnus Labuschagne was trapped plumb lbw in the next over by Cam Valente.
Renshaw nearly ran himself out with Valente just missing a direct hit from his followthrough. Thereafter it was a procession as the left-right combination of Burns and Renshaw found the boundaries with ease in a 114-run stand off 122 balls. Burns made his second straight unbeaten half-century while Renshaw brought up his first for the summer as the pair cruised to the bonus point with more than four overs to spare.
