Paddy Madden scoring the winner as Yeovil moved up to third in League One with a narrow victory over Shrewsbury,
Tom Eaves and Jon Taylor missed early openings for the visitors before James Hayter put Yeovil ahead from the spot following Marvin Morgan's handball.
Stephen McGinn connected with Joe Jacobson's cross to equalise.
But Madden took his tally of goals for the season to 23 with a stunning solo effort, keeping Gary Johnson's men in touch with the top two.
A play-off place looks more likely, however, for the Glovers, who are seven points behind leaders Doncaster and five behind second-placed Bournemouth, who both won on Saturday, but the victory took them five points clear of Tranmere in seventh.

Yeovil boss Gary Johnson told BBC Radio Bristol:
"It's a great position to be in. We have consolidated our position in the play-offs.
"That gives us a nice little buffer just in case we make any mistakes along the way.
"With four games left it's a credit to the boys that they've seen it through to this stage of the season and are still in an excellent position."
