The Baggies held off a gallant Harrow-Balmoral side to advance to the Horsham District under-17 football grand final.
Swifts put on a fourth quarter display of dominance to win 13.14 (92) to 8.6 (54).
The Southern Roos jumped out of the blocks to surprise the Baggies in the first term, holding an 18-point lead at quarter-time.
The Baggies steadied the game after the first break, wrestling the momentum back in their favour to hold a two-point lead going into the final term.
The Southern Roos could manage just one-point to Swifts’ 37 points in the final quarter.
Swifts coach Tim Chatfield said he knew his side was capable of coming back after a slow start.
“Harrow were right on top for three quarters,” he said.
“We dug deep in the final quarter to get the win. It comes down to self belief and our boys knew they were good enough to get across the line. “Before the game we focused on pressure, going man on man and talk. We really picked those up in the final quarter.”
Bourke Nicholls booted six goals and was far and away best on ground.
“It has just been a matter of time before Bourke exploded and started to dominate games,” Chatfield said.
“It was a great effort from all 22 of our players.”
The Baggies will now face Noradjuha-Quantong in the grand final on Saturday.
“It has been and outstanding year from the team,” Chatfield said.
“We are really looking forward to the whole week and the challenge the is ahead of us on the weekend.”
