WADHURST met Eastbourne at a cold and windy Saffrons Sports Ground in the opening week of the league and elected to bat first.
Andy Taylor stayed in for a respectable 22, while Bennett (1) and Wade (10) succumbed early on.
Harwood, Reid and Holland, in the middle order, made it to double figures, but wickets fell regularly to restrict Wadhurst to 136 all out.
Smith (3-26) and Mansell (3-19) were the pick of the Eastbourne bowlers.
Eastbourne's reply started brightly with the free-scoring Walker (32) setting the tone. James Harwood took 3-35, and was supported by Penny (1-38) and Ed Harwood (1-25), but it was not enough as Perkinson (62no) and Marshall (23) steered Eastbourne to victory, with 12 overs remaining.
In East Sussex Division Nine, Wadhurst II 131-9 drew with Linden Park IV 109-7.
On a damp, slow wicket and with an unsettled weather forecast, it was no surprise that Wadhurst skipper Mitchell elected to bat.
Despite the loss of two early wickets, Wadhurst made steady progress with the returning Alex Ross-Scott and debutant Rob Lucas providing the bulk of a reasonable total in the conditions.
Linden Park youngster Corner (4-10 off 5 overs) achieved remarkable figures with a wet ball.
In Linden Park's reply, their batsmen were made to work very hard by the craftsmanship of Jamie Crawford and the 22-over master class of Iain Bell.
They were supported in their parsimony by a good spell from Gavin Barrass with youngster Freddie Milsom taking three catches and newcomer Chris Ketchell getting two.
Hayes (26) and Cotterill (30) were the significant contributors in a match that ended in a draw.
Wadhurst's two Sunday friendlies were abandoned during the tea interval.
