Union have taken the Dick Hunt holiday competition by a wicket following a thrilling showdown with Albion at Awamoa Park on Saturday.
The Blues ousted Oamaru in their round-six clash at King George Park while the Mungas disposed of holders Valley last weekend.
It's the first time since a successful 2007/08 campaign that Union have laid their hands on the Dick Hunt Memorial Rosebowl trophy and captain Thomas Shields praised both sides for their gutsy performances
"We're stoked to win it. It was switching momentum all through the second innings," he said.
"We've just got to build momentum coming into the end of the season. There's no injuries so we'll be pretty much at full strength apart from the rep guys."
Albion skipper Peter Cartwright insisted his team would still be taking positives from the disappointing final defeat.
"We batted well, but we didn't bowl well at all - we had 35 wides," he said. "We fought well and we should take some confidence and some positives out of it."
Union will be welcoming back Paul Johnston, Phil Crossan and Anthony Cromwell to their ranks for the return of the Borton Cup competition next Saturday.
Despite disappointment at senior level Valley gained some consolation by taking the Senior Reserve and Second Grade holiday competitions.
