Head coach Lee Maddison was forced to travel with just one replacement due to a disappointing number of dropouts - and the traveling commitments of the league also rendering many second teamers simply unable to make the step up.
Manor now lie just 11 points above the relegation zone after Kings Norton's victory over Upton-on-Severn, with just four games remaining.
Such is odd nature of Midlands 3 West South, a win could see Park rise to sixth - but victories are a rare commodity having lost five games on the bounce.
