An ice-cool goal by Adelaide United's Argentinian import Jeronimo Neumann clinched a 1-0 win over A-League newcomers Western Sydney Wanderers on Friday night.
Jeronimo missed a contentious penalty but a minute later made amends with deft finish as the Reds banked consecutive wins to open their season.
Wanderers midfielder Mateo Poljak went within a whisker of scoring the fledgling club's first A-League goal.
But Jeronimo's classy second half strike dealt defeat to Western Sydney after their scoreless draw on debut against Central Coast last week.
Jeronimo was played into space in the 69th minute by a shrewd Iain Ramsay pass and the Argentine closed on goal as Wanderers keeper Ante Covic made a make-or-break dash towards him.
Jeronimo coolly placed a left-footer past the approaching keeper and it trickled into the net to delight the 8950 spectators at Hindmarsh Stadium.
A minute earlier, Jeronimo failed to convert a penalty after Adelaide winger Fabian Ferreira went to ground after jostling with Wanderers defender Nikolai Topor-Stanley.
While the penalty call appeared harsh, Jeronimo pushed his spot kick too close to Covic, who made a relatively comfortable save diving to his left.
The minute of action came after an opening half punctuated by skill errors and turnovers, with Poljak's near-miss in the 32nd minute a rare highlight.
Poljak launched a speculative 30 metre shot which caught Adelaide goalkeeper Eugene Galekovic off guard - the Reds captain parried with one glove and the ball bounced into a side bar.
The Wanderers also had a late chance to equalise when Labinot Haliti found space in the box in the 88th minute, but his well-connected header was cut off by Galekovic.
