Tigers' monster total dashes WA's final hopes

Western Australia's Marsh Sheffield Shield final hopes are on a precipice after Tasmania all but batted the home side out of their final-round clash at the WACA Ground in Perth.

At stumps on day two, WA were 0-46 in response to the Tigers' 514, with Cameron Bancroft (13) and Sam Whiteman (27) the not out batsmen.

Earlier Beau Webster became the second century-maker in the innings for Tasmania, bringing up his ton off 130 balls with 11 boundaries, before going on to an unbeaten 135.

The consistent Jake Doran (123) had already scored his second century of the season, frustrating WA in a 288-ball stay. 

Needing to win the match to progress to the decider, WA's slender path will now likely have to involve some fast runs and a bold declaration before either routing the Tigers or hoping they set up a final-innings chase. 

But an already tricky task has been made more difficult with the loss of key bowler Joel Paris.

WA confirmed on Sunday that injury-prone Paris had sustained a left adductor strain and would not bowl again in the match. 

Paris (2-18) had made early inroads on day one but left the field and did not return. 

The paceman may have only picked up a modest 12 wickets this season in his four Shield matches but comfortably has the best average of any bowler (19.33) with 10 wickets or more in the competition.

On Sunday his accuracy was sorely missed as Matthew Wade battled on to 90 before being caught behind off the bowling of Ashton Agar, while Test captain Tim Paine made 20.

From there it was all the Tigers, Doran proving difficult to dislodge, Webster hitting freely and even paceman Jackson Bird (64) letting loose as the latter two added 125 in a ninth-wicket stand.

Mitch Marsh was the pick of the WA bowlers with 3-84 while Agar and Cameron Gannon both took two wickets. 

Rain and bad light curtailed Saturday's action but play started early on day two to make up for lost time.
