Mid-table Scarborough faces a big run chase next Saturday after Perth dominated day one of their Premier Cricket round 8 match at Fletcher Park.
The Demons finished the first day all out for 309 in the 89th over, setting the Gulls an imposing target.
Liam Stevens (3-25) and Ed Barnard (3-60) bowled well for the visitors, who were without Perth Scorchers fast bowler Andrew Tye.
Tye suffered a shoulder injury playing for Scarborough in last Sunday’s Premier Cricket T20 matches.
Talented WA Academy bowler Andrew Rule went without a wicket for the Gulls, with 19 overs going for 71 runs.
Perth opener Jake Snadden (104) was the major thorn in Scarborough’s side, with a strong century.
