Bruce Djite became Adelaide's all-time leading goalscorer with 32 goals as the Reds went top of the A-League table with a 2-0 win over Sydney FC at Allianz Stadium.
As a team, the Reds also broke a record, becoming the first side in A-League history to post four successive clean sheets away from home.
The story wasn't so bright for Sydney, who mathematically fell out of finals reckoning moments before walking onto the pitch thanks to Melbourne Victory's 4-1 win over Wellington in New Zealand.
It would have been the outcome regardless, after the Sky Blues slumped to an equal club-record 11th consecutive winless match and fifth straight home game without a result.
With an eye to Tuesday's home clash with Pohang Steelers in the Asian Champions League - a stage on which Sydney have been performing - coach Graham Arnold rested more than half his regular starting line-up.
In their absence, Adelaide controlled play and were posed no challenge going forward.
