Horspath stretched their unbeaten run in Home Counties Premier Cricket League Division 2 to six games by bowling out bottom club Bicester & North Oxford for 88 at the Recreation Ground to set up an eight-wicket win.
The visitors had no answer to the home attack after choosing to bat as they were shot out off 26 overs with stand-in wicket-keeper Stephen Green taking five catches.
Asad Rafiq set the ball rolling when Christopher Hofen, captaining Bicester against his old club, edged behind to make it 17-1.
The pair combined again to remove fellow opener Farhaan Khan for a top score of 20, before Sravan Konidena was the beneficiary of Green's glovework as Ryan Moore fell to leave Bicester 45-3.
Asad then found the edge of Samuel Payne's bat to present Green with another straightforward catch as the visitors plunged deeper into trouble.
Liam Turnbull got in on the act, taking wickets with consecutive deliveries.
The last ball of his second over saw Daniel Savin miscue a drive to Josh Richardson in the offside to make it 72-5, before the Horspath seamer struck with the first delivery of his next over when he bowled Ibrahim Zafar for 17.
Turnbull was on fire and he enjoyed further success with Josh Towell providing Green with his fifth victim to leave Bicester in disarray at 77-7.
Oliver Ward decided attack was the best form of defence and launched a six only to be caught in front of the nets at long on by Viv Narayan from skipper Amin Rafiq's next delivery.
Turnbull knocked back Meena Waris's off stump to make it 84-9 and Amin wrapped up the innings before lunch when Ben Clark edged to Richardson, who took a good low catch at second slip.
It had been a highly efficient display by Horspath with Turnbull returning impressive figures of 4-6 from five overs, while Asad picked up 3-32, Amin 2-17 and Konidena 1-27.
Dom O'Connor and Konidena, fresh from their Home Counties club record opening stand of 139 in the rain-affected draw at home to Datchet a week earlier, set about knocking off the runs.
They had made fluent progress to 50 when Konidena was caught by Ben Clark in the deep off Waris for 23.
O'Connor continued to bat confidently, completing back-to-back half-centuries with a superb four through the covers - one of 11 boundaries as he finished unbeaten on 55 from 66 balls.
It was left to Tom Coleman to sweep the winning boundary as Horspath clinched victory - and a double over Bicester - at 90-2 in the 19th over.
Despite winning three of their last four games, Horspath remain in fourth spot ahead of Saturday's trip to second-placed Slough, who triumphed by 143 runs at Datchet.
