Sewerby entertained Dunnington on Saturday and after losing the toss took first knock.
After a brisk start with Luke Jennison making 19, they found themselves 44/3 with only eight overs gone. Russ Robinson and Mike Artley set about stabilising the innings and put on 57 for the next wicket before Robinson was out for 35.
This brought Chris Chapman to the wicket and he started to show touches of last year’s form. They had just started to put together a parternship when Artley was very unlucky to be given out caught by the keeper.
Two further quick wickets saw Sewerby at 147/7 but Shaun Acton joined Chapman and they put on 53 in 11 overs before Acton was out for 25.
Chapman had continued scoring freely and at the end of the 40 overs was 71 not out scored from 74 balls and Sewerby had reached a slightly disappointing 218/9.
Dunnington lost a wicket in the third over but the dangerous Collis King began to score freely before Shaun Acton had him stumped by Jennison for 46.
This left them at 89/3 after 24 overs but a partnership of 47 between Jack Bolam and Harwood Williams took them to 164 before Bolam was out for 60.
When Williams was bowled by Robinson for 42, Sewerby were favourites and Dunnington needed 22 from the last two overs to win.
A dropped catch in the penultimate over let them score nine, but 13 were still needed from the last over. Sutcliffe was at the crease and a towering six from the third ball of the last over cut the deficit.
Two runs from the next ball saw three needed and a dropped catch from the penultimate ball saw them scramble two more runs to bring the scores level.
Dunnington then ran a bye to the wicketkeeper on the last ball of the match to clinch a nail-biting win. Sutcliffe finished with 26 not out from 16 balls with three fours and a six.
