San Luis de Quillota holds the Primera B lead at 50 points after a six-match winning streak, yet the title race remains wide open with three rounds left as Cobreloa sits two points back following a loss to Copiapó, Magallanes trails by four after beating Recoleta, and both Deportes Antofagasta and Santiago Wanderers sit on 44 points. Antofagasta’s 3-0 win over San Marcos de Arica and Wanderers’ defeat to Curicó Unido underscore how recent results have compressed the gap among the top six sides. This bunching of contenders, combined with the direct promotion spot hinging on final positioning, keeps implied probabilities clustered near 50 percent across the listed teams.
