Belvoir completed their league season with a comprehensive eight-wicket win over Collingham to secure a third-placed finish in Division A.
Collingham captain Oliver Dyson (40) and Jonathan Todd (40) pulled their side back from the loss of two early wickets before Ben Dixon (87 not out from 55 balls) accelerated the run rate.
Blasting eight sixes in a savage knock as Collingham recovered to post a good total of 210 all out, their last two batting points due solely to the Dixon brothers.
Five overs into their reply, Belvoir were 24-2, but then went on an eight-runs-per-over rampage.
Skipper Tom Neville was already in his stride, but upon completing his 50 he went berserk, pounding one boundary after another.
At the other end, Oldfield (89 not out) played second fiddle, but took his First XI average for the season to 104.2.
The pair added 192 runs for the third wicket to tie the scores when Neville faced the 149th ball.
He simply knelt down on one knee and flat-batted an enormous straight six; the perfect finale to a hard-fought season.
