New South Wales 232 and 297 for 5 (Philippe 72, Shaw 52, Gilkes 51) lead Western Australia 333 (Green 134, Bancroft 57, Stobo 4-49, Hatcher 4-53) by 196 runs

Sam Konstas' frustrating Sheffield Shield season has ended with yet another start, after the opener made his eighth straight score between 25 and 45.

Konstas was caught at slip for 31 on Monday against Western Australia, as New South Wales kept themselves in the match on day three in Sydney.

With neither team having anything to play for other than pride, NSW went to stumps at 297 for 5 and with a second innings lead of 196 headed into the final day on Tuesday.

This season has been frustrating for the two states, with both set for new coaches and Western Australia to finish last for a second straight year.

For Konstas there will be equal frustration, even if his 660 runs at an average of 33 has him third on the overall run-scoring charts after a burst of form before Christmas.

The opener now has returns of 44, 28, 27, 35, 37, 28, 38 and 31 since the resumption of the Shield after the BBL, failing to pass 50 despite making eight straight starts.

The opener has regularly looked like he has got himself in, with Monday's innings summing up his summer when he was caught off the outside edge off Cameron Gannon.

Matthew Gilkes, Lachlan Shaw and Josh Philippe posted half-centuries for NSW after they gave up a 101-run first innings deficit.

Earlier, Cameron Green was caught behind off Charlie Stobo for 135, having added five to his overnight score after bringing up his first century of the summer on Sunday.
