Crewe battled back from two goals down before Darren Way gave Yeovil victory.
The Glovers took the lead when Danny Schofield knocked in Andy Welsh's cross at the second attempt.
Schofield made it 2-0 after good work from Paul Warne before substitute Byron Moore got the better of Craig Alcock to pull a goal back for the visitors.
Shaun Miller, who came on at the same time as Moore, turned in Anthony Elding's cross at the far post to level but Way had the final word for Yeovil.
