Maroons were brimming with confidence after crushing Nsingizini Hotspurs 8-0 on aggregate in the CAF Confederation Cup preliminary first round and they created the first real chance of the night when Devin Titus sent an overhead-kick straight at Jody February on 10 minutes.
The hosts then threatened through Terrence Mashego eight minutes later, but his effort from long range sailed over the crossbar. Sage Stephens would finally be tested on 37 minutes as he pulled off a fine save to deny Peter Shalulile, who had been played in by Lucas Ribeiro and Grant Kekana saw his header clip the top of the woodwork moments later.
It remained goalless at the break, although the Cape Winelands outfit were presented with a golden opportunity to break the deadlock early in the second half when Titus was brought down inside the penalty area. Basadien accepted the gift as he slotted home from 12 yards out to give Stellies a crucial away goal.
Bafana ba Style pushed for an equaliser in the closing stages and the visiting defence desperately cleared the ball away following a goalmouth scramble after the 75-minute mark before Stephens came to the rescue with a brave save at point-blank range to keep out Arthur Sales on 79 minutes.
Stephens stood firm once more to prevent Kutlwano Letlhaku from scoring on 89 minutes after the substitute had been picked out inside the box by Sales and Teboho Mokoena almost snatched a late leveller with a trademark shot from range that rattled the frame of the goal in stoppage time.
