Glen Harris did get the ball into the net for Slough early on as the away side started brightly at a blustery Melbourne Park but was ruled out for offside. The wind played a factor as the midfielder later swung in a free kick which was caught in the wind and nearly caught out Gavin King, guarding the home net, but the ball went narrowly over.
Richard Halle opened the scoring after the hosts had weathered a bit of early pressure from Slough. The ball was fed high into the box. Richard Halle climbed higher than Aaron Steele as the ball held up in the wind and whilst his downward header appeared to be covered by Parkin, the ball squirmed in under his body and into the net.
Ex-Rebel Tony Boot lined up for City and went close to extending the lead as he was played in behind the defence, but saw the ball stopped by the outstretched hand of Parkin as the keeper stayed upright when closing the angle.
Slough nearly got lucky with a long ball forward from Leon Woodruffe in the left back position which was nearly headed into their own net by Jerome Sobers but King was well placed and stretching up managed to hold onto the header which arrived with some pace at the keeper.
Three minutes into the second half and the home side doubled their lead. Halle stepped up and drove a curling free kick low around the Slough wall and into the corner of the net leaving Parkin with little chance.
The home side controlled the majority of the second half with Jamie Richards shooting at Parkin after George Moleski had lost the ball and Boot again brought another good save from Parkin with a low drive which the keeper pushed away.
The introduction of Carbon did bring a degree of directness to Slough's play as the right sided player was always keen to push forwards and it led to Slough getting the ball into the net again, but Ian Hodges was offside as he received the ball from Carbon following a run from outside the box.
Slough finished the game with ten men as Hodges received his second yellow and was dismissed from the pitch.
