After a goalless first term, the Bombers utilised a strong breeze at Quantong to full effect in the second quarter, booting six goals and opening up a 32-point lead by half-time.

Noradjuha-Quantong's second quarter proved to be the game-defining run, as the match finished with the same 32-point margin, 11.10 (76) to 6.8 (44).

It was the first time the Bombers have beaten a top-five side this season.

Bombers coach Gareth Hose said it was the best win from his two seasons at the club.

"The way we executed, and played the style of footy we wanted to play, was just excellent," Hose said.

"Considering the outs that we had ... this is the best win I've had since I've been coach of the club."

The victory came despite the absence of important midfielder Nathan Byrne, and the club's two leading goal-kickers, Shane Oakley and Jye Walter.

Youngster Riley Dunlop was named the Bombers best for his work at half-forward, while key defender Zane Batson did a remarkable job on Jeparit-Rainbow's Peter Weir.

After Weir booted 10 goals against the Bombers in round three, Batson was able to earn redemption on Saturday, keeping Weir goalless for the first time this season.

"I'm really, really proud of his effort," Hose said. "He's grown as a player and that was clearly evident on Saturday."

The win propelled the youthful Bombers back into sixth place on the ladder, after Kalkee lost to Edenhope-Apsley by 55 points.

The Saints came out firing and kicked nine unanswered goals in the opening term against Kalkee to shock the home crowd.

The big bodies of George Walker and Matt Butler caused problems for the young Kees' back line - the pair bagging five and four goals for the day respectively.

When the Kees did attack they were hampered by a noticeable head wind and only managed two behinds, entering the first break 54 points behind, 0.2 (2) to 9.2 (56).

With the win behind their backs in the second term, the home side clawed their way back into the contest.

The visitors were kept scoreless in the second quarter, but Kalkee failed to capitalise on their opportunities, booting two goals and six behinds for the term.

The Saints turned the tables in the second half, keeping the hosts scoreless in the third term and running away with the game.

Lachlan Middleton appeared at every contest in the engine room and was named the Saints' best on the day.

Kalkee's Matthew Nield and Ben Lawson provided late highlights, with classy goals in the game's dying minutes. But it was too little too late, as the final siren ended a game Edenhope-Apsley had all but secured an hour earlier.

Elsewhere, Harrow-Balmoral and Swifts celebrated comfortable wins against Rupanyup and Pimpinio respectively.
