Macarthur's debut A-League season continues to go from strength to strength after Matt Derbyshire's brace secured a 2-0 win over Perth Glory.
The Bulls, who made their bow in December, climbed to second thanks to a comfortable home victory on Good Friday.
The new boys have now won three in a row in the competition for the first time and sit only three points behind leaders Central Coast Mariners.
Macarthur's first meeting with Glory went entirely to plan as in-form Derbyshire broke the deadlock after 10 minutes.
Benat Etxebarria, the only man to attempt 1,000 passes in the A-League this season, spread a fine ball out to Ivan Franjic, whose header back across goal from the right was met by Derbyshire, first to react to prod in off the underside of the crossbar.
Macarthur might have added to their lead long before the second deservedly arrived on the stroke of half-time, albeit in contentious circumstances.
Markel Susaeta bought a cheap foul from Sebastian Langkamp in the area and Derbyshire coolly sent the resultant penalty straight down the middle for his 10th goal of the season - trailing only Jamie Maclaren (12) - to seal the points.
