Bridlington travelled to local rivals Folkton and Flixton and after losing the toss were asked to bat first.
There was 17 runs on the board when the first wicket fell, as Casey Rudd departed for four.
Simon Leeson (65) continued his good form and with John Major (26) added 65 for the second wicket as they moved the score to 82/2 but Bridlington lost two quick wickets and were 119/4 after 30 overs.
The Bridlington batsman were struggling to score runs from the economical Mann, who bowled his 12 overs for a miserly 21 runs and picked up two wickets.
Nick Tennant (39) and Sam Edmundson (32) added a useful 47 runs towards the end of the innings and Bridlington passed 200 in the 48th over, finishing the innings on 202/9.
Nesfield, Mann and Zakrzewski all picked up two wickets each.
The hosts reply got off to a fast start with Walmsley and Elvidge punishing any slightly wayward bowling from Bridlington. They put on an excellent 114 for the first wicket before Walmsley fell or 44.
Zakrzewski helped Elvidge move the score along before Elvidge was well stumped by Adam Ykhlef off the bowling of Steve Janney for a fine 83.
Janney then removed Malthouse (16) and Zakzrewski (37) and with Will Hall removing former Bridlington player Scott Cooper, well caught by Leeson, the hosts were 197/5.
However, the home team held their nerve and reached the target with 5.4 overs to spare. Janney was the pick of the Bridlington bowlers with 3/38.
