Sewerby travelled to Sheriff Hutton Bridge on Saturday and, having won the toss, asked them to bat first.
Despite good efforts from the first four bowlers it was not until the 23rd over when the first wicket fell, with George Worthy having opener Dave Bradshaw caught for 31 with the score at 80 before fellow opener Paul Oldfield was run out for 43 with the score on 90.
Home skipper Adam Fisher was scoring runs freely and helped by Rob Pinder (24) and Matt Fisher (24) took the score to 215/4 with six overs remaining.
Russ Robinson returned to the attack and took four wickets in four overs, including Fisher for a fine 93, as Sewerby managed to restrict the Bridge to 246/8 after the 50 overs. Robinson finished with 4-60 from 13 overs.
Sewerby needed a good start and the Tennant brothers, Sam and Mark, put on 38 in 10 overs before Mark was out for 10.
Sam continued to bat beautifully despite receiving a cut eye from a short ball but he was out for 53 with the score at 82.
Mike Artley and Ben Dobson shared a partnership of 103 in 20 overs to keep Sewerby in contention before Artley was caught in the deep for 73.
To their credit Sewerby kept pressing for runs but two run outs, Dobson for 39 and Russ Robinson for 18, left them needing 22 runs from the last two overs.
Tom Chippendale (27 from 21 balls) was run out from the third ball of the last over and Sewerby were left three runs short at the end of the 50 overs after what was a great effort.
