It was a heartbreaking loss for the Bluebags in the end of the Freebody Oval clash, going down by four runs after losing their last six wickets for just nine runs.

They bowled well in the first innings as well, removing former skipper Blake Dean before he could do further damage for 57, and restricting the competition heavyweights to 7/222 off their 50 overs.

After Russo and teammate Dean Solway put on 98 runs for the second wicket in their innings, the hosts found themselves at 4/217, but a nightmare batting collapse- including three ducks and three run outs- proved the ultimate sword.

But on a personal note, Russo was happy to score his first century in four years, ironically also against Weston Creek Molonglo, and said his exposure to South Australian players in Adelaide last season had made him a more professional cricketer.

"I spent a lot of time state with players Sam Raphael and Trent Lawford and one of the coaches Ant Botha, and just to see the professionalism shows what it's all about really," Russo said.

While he scored almost half of his team's runs last Saturday, he said he blamed the tight loss on himself, and thought he should have stayed in the middle for longer to amass more runs.

"I think I was a bit of a problem being in, and I should've batted all the way through, but I put a lot of pressure on myself for letting the game go by more so than the others," he said.

"I was very disappointed, even though I scored those runs. I was devastated to be honest."

Batting has been the let down for Queanbeyan after two rounds this season, with a top order collapse leaving them nervous at 5/37 before they came back to chase down 88 runs in the first match, while the middle order and tail failed against Weston.

It was been a different story in their bowling ranks though, after they rolled North Canberra Gungahlin for just 84 two weeks ago, before restraining Weston to a chase able total.

But Russo said the mixed results were due to his side being young, and he was confident they would improve as a unit throughout the season.

"I'm the second oldest player in the side at 23 years of age, so that shows something," he said.

"I think it's just youth. We've been good in the field, and the bowlers have been bowling to Tubby's [captain Sam Taylor] plans, and that seems to be working."

Meanwhile Queanbeyan picked up wins in third, fourth and fifth grade last week, while the second grade side suffered its second loss in a row.
