Tranmere missed the chance to go top of League One following defeat to Port Vale.
Rovers found themselves behind after just 31 minutes when Jeff Smith fired home after good work from Stefan Moore and Danny Whitaker.
Smith then turned provider just after the interval when he set-up Leon Constantine (pictured) to fire home.
Chris Greenacre pulled one back for the home side just before the hour, but they could not find an equaliser as Vale claimed the victory which takes them into seventh.
The other game on Friday evening saw Northampton and Bradford play out a goalless draw at The Sixfields Stadium.
The point sends Bradford into fourth place.
