Opener Jake Weatherald anchored the Redbacks' innings, scoring a fine 103 off 114 balls.

Weatherald 100 v NSW

He was overshadowed only by Player of the Match Alex Ross who scored a blistering 110 in 85 balls to set up a formidable total of 6-346 for the Blues to chase.

Despite the return of Mitchell Starc from a foot injury and captain Peter Nevill electing to bowl first on a cloudy morning at the compact Hurstville Oval, they could not stop the threat of the free-scoring Redbacks.

They raced to a 100-run partnership through Carey (60 in 50 balls) and Weatherald before the former was bowled by a fine delivery from Sean Abbott which angled into the off stump.

Ross 100 v NSW

Cue Ross who was able to score through all parts of the ground, smashing Nathan Lyon for an Australian List A record of 32 runs in a single over.

The Blues looked comfortable in their chase from the outset, with a Daniel Hughes century and a 189-run partnership with Kurtis Patterson.

However, they then lost two wickets in two balls which threw the match back in the Redbacks' favour which included a Mennie hat-trick chance - his second of the tournament.

The menacing quick struck through the latter overs and finished with figures of 4-53 to secure his side victory and first place on the JLT One-Day Cup ladder.

The Redbacks next face the Tasmanian Tigers at North Sydney Oval on Tuesday.
