A superb 155 from captain Adam Voges has given Western Australia a commanding 118-run first innings lead against New South Wales at the WACA Ground.

The Sheffield Shield clash was delicately poised coming into the third day with WA resuming at 5-263 in reply to NSW’s 344, but Voges and wicketkeeper-batsman Sam Whiteman batted through the entire first session to give the Warriors first-innings points.

Even though Whiteman fell short of his maiden first-class century on 88 in the afternoon session, Voges continued his dominant innings as WA finished their first innings on 462 against the top-of-the-table Blues.

WA did have a slice of luck early in the day when Whiteman was given not out despite appearing plumb in front facing Doug Bollinger and then Trent Copeland looked to have Voges out caught behind.

However, the umpires decided both would stay and the batsmen took full advantage.

By lunch, Voges and Whiteman had advanced the score to 5-366 with the skipper notching his century.

The pair continued on after the break and Whiteman looked on target for his maiden ton, but fell short when bowled by spinner Manjot Singh.

Voges continued on, though, ending up with 155 and receiving good support from Jason Behrendorff (29) and Ryan Duffield (16).

Voges opened the day on 73 and quickly brought up his century on Saturday morning with the 34-year-old tallying 681 runs this season in just six matches at an average of almost 76 to be the third-highest run-scorer in the competition.

The 21-year-old Whiteman continues to emerge as perhaps the cleanest keeper in the country, but his batting has come on in leaps and bounds amassing 591 runs with six half-centuries at an average of more than 59.

Sean Abbott was the pick of NSW’s bowlers with 4-71 while Singh took 2-163 from 35 overs.
