LONG-TIME leaders Prestwich dropped to third in the Greater Manchester Cricket League Premier Division following a heavy defeat at home to bottom side Unsworth.
Andy Bradley's men were bowled out for 46, falling 157 runs short of their target.
Unsworth captain and pro Chris Williams smashed 117 not out in their total of 203-6, with Mike Finan taking 3-27 for Prestwich.
Only Ryan Stanbury (22) made it into double figures for the home side as Williams (4-25) and Ian Hall (5-16) shared the wickets, taking 19.3 overs to finish them off.
The result helped Unsworth haul themselves off the bottom of the table, while Prestwich's third straight defeat left them eight points behind leaders Egerton with nine games of the season remaining.
Prestwich, who host Egerton on the final day of the season, now know that the destiny of the title is out of their hands after looking well set to claim the inaugural Premier Division championship for the majority of the season.
Stand, meanwhile, remain on top of the Second Division despite falling to a three-wicket defeat at home to Edenfield.
Matt Curphey made 43 and Ben McManus came in at number 10 to hit 31 from 33 balls to push Stand's total up to 181.
McManus (2-16) also removed both Edenfield openers while Ali Azmat took 5-47, but the visitors made it past their target with 23 balls remaining.
