Adelaide secured their fourth successive victory with a 2-1 win over Newcastle Jets today to move three points clear at the top of the A-League.

Matthew Leckie headed home the opener in the 23rd minute before Argentinian midfielder Marcos Flores added a second midway through the second half, picking up the ball in midfield before charging at the Jets defence and then slotting a left-footed effort into the back of the net.

The Jets pulled a goal back deep in stoppage time through substitute Sean Rooney, who pounced on an error by defender Cassio, but it was not enough to deny Adelaide the three points.

The Reds have made a fine start to the season with four wins and two draws and top the standings with 14 points, three ahead of Perth Glory and Central Coast Mariners. The Jets, meanwhile, are still searching for their first win of the season and are ninth with three points.

In the day's other game, Wellington Phoenix returned to winning ways with a 2-1 triumph over strugglers Sydney FC at Westpac Stadium. Paul Ifill put the hosts ahead from the penalty spot in the 50th minute after Chris Greenacre had been brought down by Bruno Cazarine.

Cazarine made amends 17 minutes later when he grabbed the equaliser following a clever one-two with Mark Bridge, but the Phoenix scored the winner in the 72nd minute when Nick Ward fired high into the back of the net.

The win was Wellington's first after two successive defeats and means they climb to fifth, while the winless Sydney remain rooted to the foot of the table.
