Adelaide United's breakthrough 1-0 win against Perth on Sunday night lifted the Reds from the bottom of the A-League ladder and left the Glory there instead.
Spaniard Pablo Sanchez scored the winner in just the third minute to give United a first win of the season, and the first under new coach Guillermo Amor.
Adelaide (six points) climbed from last to eighth, ahead of now-bottom Perth (four points) and Central Coast (five points).
Sanchez could have scored more - he also had three close-range headers which missed their mark and a right-footed blast tipped over - in a Coopers Stadium fixture played in searing heat.
Kick-off was delayed by two and a half hours because of near-40 degree temperatures, and wicked winds accompanied the heat.
But Adelaide adapted to the harsh conditions well - though their Red Army supporter base missed their best performance of the season as they walked out on 30 minutes in the latest protest against Football Federation Australia's fan ban process.
The Red Army left a banner with the message `FFA: Can You Hear Us Now?' but at least they saw the defining goal, which came as the 6,205-strong crowd were settling in their seats.
Sanchez scored in a tick over two minutes with a classy chip after defender Michael Marrone played a hopeful long ball from the halfway line.
The ball tracked toward Sanchez and Perth defenders Marc Warren and Antony Golec, who tried to sandwich the Spaniard.
But the United attacker spun between them, followed the ball to about five metres out and then coolly chipped over advancing Glory goalkeeper Ante Covic.
Sanchez, in just his second start this season, was an ever-present danger along the right flank while Adelaide midfielders Marcelo Carrusca, starting for the first time in a month, and Cirio were also constant threats.
Defender Marrone was a standout and goalkeeper Eugene Galekovic made five saves as Adelaide transferred a weight of possession into a win which lifted a collective weight from their shoulders.
