It was a disappointing day at the office for UWA as they fell to their first defeat in three games with a 3-0 loss to Western Knights.
Uni started derby day brightly, with a series of corners following a pair of blocked goal-bound shots causing serious issues for Knights keeper Sam Stone.
UWA almost opened the scoring after only five minutes, with the intricate play from Tim Robertson and Michael Vlasich opening up an opportunity for Alex Kretowicz just inside the area, but his powerful strike was acrobatically tipped over the bar by Stone.
After the two sides enjoyed a few half chances, some neat play from Lloyd Prout down the right wing and eventual cross found Robertson, with his right footed shot striking the upright and out for a goal kick with 34 minutes played as they piled on the pressure heading into half-time.
A cagey opening stanza was pierced by Western Knights as they grabbed the lead shortly after the restart. The left side was caught out of position following a ball over the top with former UWA player Jack Rycroft slotting home from inside the box to make it 1-0 to the hosts.
Knights immediately doubled their advantage after Carlos initially saved Paul Lloyd's free-kick, with the ball falling into the path of Tom Southgate who tapped into an empty net.
Knights attacker Adriano Jelenović rounded out the result latching onto an intercepted pass deep in UWA's defensive half and made it 3-0 at the hour mark.
A day where Uni had their chances early on, but eventually their inability to capitalise in those crucial moments cost the visitors dearly.
Michael Janssen's men will look to bounce back and return to the winner's circle next Saturday at The Mac where they take on South West Phoenix.
In other results, Gerhard Janssen's reserves narrowly lost 2-1 despite Sam Holden continuing his goalscoring ways. The 18's enjoyed a confidence boosting 4-0 drubbing of Western Knights thanks to a brace each to Enrico and Isaak.
