UWA have progressed to Round 5 of the FFA Cup following a hard-fought win over Kelmscott on Easter Monday.
Uni prevailed in testing conditions, with the sun and Kelmscott providing a stern test for the lads following a busy pre-season schedule.
Michael Jansenn's men were very much on top in the first-half, with Alex Kretowicz busy early and denied on a few occasions by some superb goalkeeping in one-on-one situations.
The frustration continued when Tristan Taylor's shot from inside the area cannoned off the crossbar, but Kretowicz wasn't to be denied again after 25 minutes.
Taylor found himself in space following a dashing run down the right-wing and delivered a peach of a cross for Kretowicz, with the star man this time making no mistake as he dispatched into the bottom right corner.
UWA continued to pepper the Kelmscott defence, but the visitors were holding firm as the score remained 1-0 at the break.
The second stanza saw a much more even contest, with the Roos asserting themselves in the final third more consistently. However, they weren't able to muster any clear-cut chances with only one shot on target, which Rhys Macfarlane dealt with expertly.
Conway almost doubled the hosts lead on the hour mark, with Joe Hayden's whipped corner finding the winger clear at the front post, but his glancing heading was acrobatically swatted away from the top corner at the last moment.
Uni had a few late chances to put the game to bed, with Conor Devlin unlucky not to be awarded a penalty, but Kelmscott remained resolute and pushed hard for an equaliser.
Kretowicz's early strike proved the difference as UWA claimed their first clean sheet of pre-season and ended preparations for the 2018 State League campaign having tasted defeat just once in the Night Series Final.
The triumph was another character-filled performance from the boys, who were without pivotal figures Luke Randazzo and Tim Robertson on the day, but the pair will be back for the season opener against Fremantle City this Saturday at Hilton Reserve.
