Swansea City stayed top of the Championship but could not move clear after a goalless Welsh derby with Wrexham, a night short on chances and long on argument over a late challenge by Ben Cabango.
Neither goalkeeper had a save to make until late on, when substitute Zan Vipotnik could only direct Moussa Yeo's cross at Anthony Patterson, and Kieffer Moore forced Lawrence Vigouroux into a stoppage-time stop. It was Vigouroux's fourth successive clean sheet as Swansea extended their unbeaten start to the season.
Phil Parkinson's Wrexham, who had recorded their first win of the season at Millwall on Wednesday, took the point but left convinced they should have been playing the closing stages against ten men.
