He advanced from 10no overnight to be dismissed for 80, caught at cover from a mistimed drive during Friday's middle session.

His knock helped WA to a 17-run first-innings lead, making 243 in reply to Tasmania's 226.

Hilton Cartwright added 35 before being the first wicket to fall on day two, while an unbeaten 26 from Matt Kelly allowed the Warriors to overtake Tasmania's score.

Gabe Bell took 3-45 for Tasmania, Simon Milenko 2-28 and Sam Rainbird 2-51.

Tasmania made a shaky start to their second innings, losing Alex Doolan for six and Beau Webster for 12 to be 2-31.

But Jordan Silk (46) and Jake Doran (13) survived to stumps with Tasmania at 2-82 with an overall lead of 65 runs and eight wickets in hand.

The day was about Marsh, though. The 34-Test veteran needed to impress and he did in his 140-ball knock that included 17 boundaries.

He gave one chance on 71 but his front foot driving and strokes off the back foot showed he was finding good form.

The 35-year-old was just glad to spend some time in the middle and get amongst the runs.

"It was just nice to get out there and spend some time in the middle, which I haven't done over the last few weeks," Marsh said.

"It was nice to play with a bit of freedom and I felt good. I'm just enjoying playing for WA again with the boys and having a bit of fun out there."

Day three action resumes from 10:30am AWST.
