One point separates them. Blackwood made sure it stayed that way

George Blackwood's football journey has taken him from the A-League to Indonesia, Malta and back again. Now, he's driving WT Birkalla's unlikely title charge.

The former Sydney FC premiership winner continued his outstanding season on the weekend, converting the decisive penalty in a hard-fought 1-0 victory over Croydon FC that kept Birkalla at the summit of NPL South Australia.

Blackwood now has a joint league-high 11 goals for the campaign and continues to prove one of the competition's most influential signings.

The pressure isn't easing, though.

MetroStars remain just one point behind after edging FC Beograd 2-1. Binyam Kebede and Hamish Gow found the net as the perennial contenders kept pace with the leaders.

Adelaide City also remain firmly in the conversation.

Domenic Costanzo starred with a brace as City dismantled Sturt Lions 4-1, leaving them four points adrift of top spot with the title race continuing to tighten.

Joint Golden Boot leader Joshua Mori was among the goals once again as Campbelltown City comfortably defeated lowly Para Hills Knights 3-0. The prolific striker continues to deliver week after week for the reigning champions.

West Adelaide claimed one of the results of the round, overcoming Adelaide United 3-1 thanks largely to a clinical double from Maksim Ivanic.

Meanwhile, Playford City showcased the resilience that has become synonymous with the club's remarkable rise after overturning a two-goal deficit in their 2-2 draw against Adelaide Comets.
