'Incredible': Young gun humbles Smith and Warner in stunning scenes

NSW's star bowling line-up were left with it all to do on Wednesday after the Blues mustered just 237 in their must-win one-day cup match against Tasmania at North Sydney Oval.

Test batsmen David Warner and Steve Smith both failed with scores of four and nine respectively, in their first one-day outings for the summer as NSW were dismissed off just 43.1 overs.

Warner's lean trot continued when he miscued a pull shot to offer a simple caught and bowled to Riley Meredith (2-65).

The Tasmanian paceman then had Smith caught at square leg as world's No.1 Test batsman sought a third successive boundary off his pads.

NSW included Test fast bowlers Pat Cummins and Josh Hazlewood for their first starts since the Ashes, while fellow tourist Mitchell Starc coming off a 10-wicket haul for the Blues on the weekend and Nathan Lyon's offspin offers a change of pace.

After being sent in to bat, NSW stumbled their way to 5-136 before ever-reliable wicketkeeper/batsman Peter Nevill steadied the ship to be the last man dismissed for 56.

Nathan Ellis takes career-best haul

In-form opener Daniel Hughes was unlucky to be given out caught behind for 44, with replays suggesting he missed the ball.

Youngster Matthew Gilkes looked good before he fell for 43.

An impressive Tasmanian bowling effort was topped by medium-pacer Nathan Ellis who took career-best figures of 5-38 from 8.1 overs.

The Blues are fifth in the one day cup standings after three successive losses followed their opening match victory while the Tigers are bottom with just one win from their four games.
