Droitwich will now have home advantage against York, the North champions, in the RFU Intermediate Cup semi-finals on March 31 and they are now just one game away from a second successive appearance at Twickenham. Last season Droitwich were beaten finalists in the RFU Senior Vase.
Whitchurch knocked Droitwich out of the North Midlands Shield earlier this season but they failed to recover from a scrappy first half performance into a stiff and bitterly cold wind.
Droitwich were sharper and took the lead when flanker Aron Middleton rumbled over from a fourth minute line out and centre Ed Wormington added a difficult conversion.
Droitwich used the experience of tighthead prop James Shewell and back-row forwards Pete Knight and Phil Horton to keep Whitchurch under pressure which produced a close range try for lock Sam O’Brien.
Despite further pressure Droitwich failed to add to their 12 points in the first half which gave Whitchurch, with the wind at their backs, hope.
But the game swung decisively in Droitwich’s favour after 53 minutes when they were awarded a penalty try after wing Phil Shore was high-tackled by Whitchurch number eight Jack Furnival.
To make matters worse for Whitchurch it was Furnival’s second yellow card offence of the afternoon which meant they had to play the final 27 minutes with 14 men.
Despite that handicap Whitchurch produced their best rugby of the match in the final quarter and reduced the lead when tighthead prop Tom Hale went over from close range and Ryan Horton converted.
But further pressure went unrewarded and Droitwich were able to close out the game and move one step closer to another trip to Twickenham.
