WA are 7-334 at stumps on day one after being sent in to bat on a green-tinged Blundstone Arena pitch in Hobart.

Philippe top scored with 76 and struck 12 fours in his second half century in as many innings.

"We're pretty happy with how it went. The wicket went better than we were expecting. It's a nice position to be in," Philippe said.

The youngster put on a valuable 82 run partnership with D'Arcy Short, who bashed 49 from 52 deliveries, to help guide WA's total towards 300.

The Tigers and WA, placed third and fourth respectively with two rounds to play, are gunning for a win to keep their chances of a Shield final berth alive.

The Warriors lost opener Cameron Bancroft (27) and captain Mitch Marsh for six as they reached 3-91 at lunch.

Hilton Cartwright (66) and opener Sam Whiteman (55) steadied the ship with half centuries in the middle session.

Joel Paris (25*) and Matthew Kelly (9*) survived until the close of play, with the action resuming from 7:30am AWST tomorrow.
