Mainstay Group returned to Birmingham for the third successive week.
The barristers of No 5 drifted into the ground as the game started and in future should seek out sympathetic judges who will adjourn early for the cricket to start on time.
Despite the late show No 5 set a total of 139 for Mainstay to chase.
Poor shots and failure to follow captain’s orders to play straight and sensibly meant Mainstay fell short.
There were also unconfirmed rumours of a pavilion strop by Mr Horne who was run out without facing a ball with Mainstay losing by seven runs.
Surveyors Savills returned to winning ways with captain Tom Burn back in the runs.
Phoenix made it three wins from three in the tournament this year by beating semi-final rivals Deloitte.
Boundary Sports were the other major benefactors with Steve Clevett committing the schoolboy error of forgetting his kit.
He had to stop off en-route to the ground for a new set of whites.
Deloitte could only make 64 in the face of some good bowling.
Darren Kok was amongst the runs and steered Phoenix home by eight wickets.
