Leyton Orient defended valiantly to claim a 2-1 home victory against Carlisle.
The hosts were often at full-stretch before clinching their fourth win in five matches against a hard-working and well-organised Carlisle side.
The visitors went ahead after 21 minutes with their first shot at goal, a superb 35-yard effort from defender Brian Shelley.
But Orient were level four minutes later when Jabo Ibehre latched onto a pass from Chris Tate and lifted the ball over Carlisle goalkeeper Matt Glennon.
Tate was again the provider for the hosts' second as he chased a loose ball to the touch-line and crossed for skipper Dean Smith to scramble the ball past Glennon.
United midfielder Mark Hudson rattled Orient's crossbar as the interval approached and Carlisle went on to spend much of the second period in opposition territory.
Home goalkeeper Scott Barrett preserved the lead with a superb 70th-minute tip-over from Jon McCarthy and the Cumbrians' second-half efforts went unrewarded.
