Rathbones Old Victorians have completed the treble by beating Odey ORs by 31 runs in the final of the Channel Islands League.
Batting first, the OV's captain Peter Gough made 86 in an opening stand of 171 with his brother Jonny.
The Jersey side finished on 273-9 from their 50 overs at Grainville despite figures of 6-31 from Tim Duke.
Odey ORs lost early wickets in the chase and were bowled out in the final over for 242.
The win means the OV's have secured the treble of the Jersey Premier Division, Senior Cup and the Channel Islands League.
Gough said: "It was a good pitch to bat on and we needed to make sure one or two batsmen got set and made decent scores.
"It was a brilliant pitch actually. Grainville's come in for a little bit of criticism for being a little bit slow, but today's pitch was superb and there was good bounce all day.
"We had a couple of really good partnerships and that was the key I reckon."
