Leyton Orient's worrying slump continued as Cheltenham continued their push for a play-off place with a 2-0 victory.
The Robins took the lead after 38 minutes following a set-piece. Mike Duff's shot hit the post and then defender Jamie Victory followed up to scramble the ball home.
Pressure from Orient was rare from here on and as they reorganised to bring on an extra striker, Town doubled their lead.
Lofty striker Julian Alsop met with Tony Naylor's low cross to ram in his 12th League goal of the season after 68 minutes.
Orient showed no hint of the form that has carried them to a fourth round FA Cup tie at Everton next week, and with three of their next four League matches away from home, Paul Brush's side would appear to be facing a possible relegation struggle.
