Young talent remains at the forefront of Osborne's campaign this season.
The side notched up their fifth win on Saturday defeating Brock-Burrum to keep them just one step off leaders Rand.
Chasing a small target of 59, Osborne made 63 off 19 overs at home.
Tom Howard made 30 runs not out, while Daniel Kennedy, Ed Perryman and Jo Perryman all took two wickets each.
Osborne's Darren Howard said it's been great to give the club's young talent opportunities on the field this season.

"I think that's the key for us at the moment, to give them time at the crease," Howard said.
"Sam McCready came back in the side on the weekend and is a talented young player and Joe Perryman and Chad Fuller have been good all year.
"We're giving these guys game time and hopefully it'll pay off for us."
Tim Doherty and Trent I'Anson took one wicket each.
Brock-Burrum were missing several players due to harvest commitments, while players were greeted by a spectator in a header at the ground in Osborne.
"I think it just sums up country cricket," Howard said.
Osborne were coming off the back of a narrow loss to Walbundrie last round, which Howard said installed some confidence in the side.
Rand defeated Walbundrie, Henty rolled Culcairn, Lockhart upstaged Holbrook and TRYC were too strong for Walla.
