Second half goals from Carlisle United's Jamie Devitt and Hallam Hope condemned Cheltenham Town to a third successive defeat in League Two.
The result leaves Michael Duff's Robins in 21st and only two points clear of the relegation zone ahead of three home games in a row against sides around them in the table, with Macclesfield Town, Cambridge United and Yeovil Town all visiting the Jonny-Rocks Stadium.
Defender Charlie Raglan made a solid start to his loan spell from Oxford United, but there were not many positives for Duff at Brunton Park, where Cheltenham have now gone 12 Football League appearances without a win.
Carlisle United (4-3-3): A Collin; G Miller (G Glendon 81), T Parkes, A Gerrard, D Grainger; R Slater, K Etuhu, J Sowerby; L McCarron (M Jones 75), J Devitt (C Simpson 83), H Hope. Subs not used: L Gray, J Kennedy, M Gillesphey, J Egan.
Cheltenham Town (3-4-1-2): S Flinders; C Alcock (K Dawson 86), B Tozer, C Raglan; R Broom, C Clements, C Thomas, C Hussey; B Waters (J Maddox 65); L Varney (A Addai 65), T Barnett. Subs not used: R Lovett, J Mullins, J Forster, C Pring.

McCarron on the right, Slater bursts into the box and the cross is behind Devitt, but he’s there to control it and his shot goes in off the left post
