Sagar Udeshi’s 4-19 in 12 overs, backed by two wickets apiece from Errington and Dick, helped Ryhope dismiss the home side in 41.4 overs.

Marsden were the main movers on the day and are certainly not out of the promotion race.
With teams all around them either drawing or losing, their win at home to Peterlee has immersed them right into the thick of it.
They bowled out the visitors for just 101, despite 60 from Michael Thorpe, with Jacques Porter (4-18) and Sura Malinga (3-15) doing the damage.
A calm 34 from Malinga and a useful 21 from opener Christopher Mann, when wickets were tumbling all around them, edged Marsden home by two wickets as Aaron Shellie (4-41) and man of the match Thorpe (3-17) produced plenty of problems.
The defeats for Ryhope and Peterlee have let Whiteleas join the promotion push, moving up to second place, just nine points behind Littletown.
