An exhausted Marconi has come away with a 1-0 win over South Melbourne in the National Soccer League match at Marconi Stadium.

The deferred round 20 fixture was the Stallions' second game in four days and the exhaustion began to show near the end.

The victory secured Marconi a place in the finals with only two matches left in the season - tough away assignments against Adelaide and Perth.

The win came at a price for the home side, however, with striker Jeromy (Jeromy) Harris being carried off with ankle ligament damage in the 26th minute.

Brad Maloney found the back of the net in the 38th minute to secure victory.

Nine minutes into the match, Maloney found the net but referee Mark Shield ruled offside.

South Melbourne had a chance midway through the second half when both Kristian Sarkies and Con Boutsianis took shots but both were impressively saved by Marconi goalkeeper Michael Turnbull.

Marconi moved to 37 points on the NSL ladder, in equal third place with Sydney United, still with one more deferred match and a bye up its sleeve.
