Western Australia boosted its chances of reaching the Pura Cup final with an outright win over New South Wales at the WACA Ground.

Set just 108 runs to win by the Blues on the final day, the Warriors edged to victory with eight wickets in hand.

After a dashing century by rookie James Packman helped NSW make 409 in its second innings, the Warriors survived some tense moments early in their chase to finish on 2-108, with Murray Goodwin on 49 and Marcus North on 44.

The Blues' hopes were raised when the Warriors slumped to 2-25, before Goodwin and North steered the home side to victory.

The win takes the Warriors to the head of the Pura Cup ladder on 36 points, ahead of Queensland (34) and the Blues (28).

Although NSW opener Greg Mail hauled himself out of a form slump with a fighting century and Packman blazed his first hundred for the Blues, the home side was always in control after leading by 302 on the first innings.

Mail (101) and Blues skipper Brad Haddin (52) made an encouraging start to the day as they tried to save the match, but the captain's dismissal after half an hour of play was a major blow to the Blues.

Having notched his half-century from the previous delivery, Haddin holed out to Shaun Marsh at mid-off from the bowling of a fired-up Brad Williams.

Although Packman joined Mail and the pair saw the Blues through to lunch, the former's dismissal in the first over after the break was fatal for the Blues.

Mail went into the match without a half-century this season and averaging just 14 with the bat.
