South Perth all-rounder Hilton Cartwright shined on his home deck on the opening day of WA's Toyota Futures League match against the QAS at Richardson Park.
Two days after scoring a match-winning century for the Sky Blues against Fremantle on the same ground, the WACA Development Squad member captured 4-54 to keep the hosts in the contest.
QAS recovered from a shaky start when they fell to 3-53 to go to stumps on 8-300. Dom Michael top-scored with 104 at first drop, while Chris Lynn continued his love of facing WA bowlers, chipping in with 83.
Australian Under 19 batsman Nick Stevens scored 48 and opener Andrew Gode made 35. University left-arm quick Dave Vernon took 2-31, while Ryan Duffield and Andrew Rule picked up a wicket each.
