Assani Lukimya gave Liaoning the lead from the penalty spot but two goals in three minutes from Gao Lin and Riacrdo Goulart saw the six-time winners of the CSL claw their way to a win that keeps them within three points of top spot.

a win that keeps them within three points of top spot（定语从句）

上句中的先行词是 a win 还是 win？

在扩展一下，定语从句的先行词包括限定词在内吗？(我指的是限定词，不是修饰词)

谢谢老师。
