Sunshine United has lost ground on the top two in the Victorian Turf Cricket Association senior division.
United was made to pay for its patchy batting innings.
The Tigers could only muster 161 – a target which opponents Seddon had little trouble chasing down in the one-day game at Selwyn Park on Saturday.
Roshan Anuruddha and Leigh Sheridan did their best to lift United to a strong total. The pair combined for 97 for the third wicket.
Anuruddha was the aggressor in the partnership, making 61. Sheridan was a calming influence en route to 33.
Both Anuruddha and Sheridan went out with the score on 127, which sparked a collapse in the United batting order.
The Tigers lost their last eight wickets for 34.
Seddon passed the target with three overs to spare. Damith Priyadarshana led the way for the Dockers with 57.
Thomas Duxson was the pick of the United bowlers with 2-26 off eight.
United will make the trip to St Albans in the final two-day game before Christmas, starting on Saturday.
