James Lane The 2025 Australian Baseball League season ended with one of the most unlikely championship outcomes in recent memory, as the Adelaide Giants upset the Sydney Blue Sox to claim the ABL title. Sydney entered the Championship Series as clear favourites after finishing the regular season with a dominant 24–14 record. Adelaide, by contrast, scraped into the postseason with a 19–20 mark and were widely viewed as underdogs heading into the three-game series in Sydney. Ov

Round 10 brought the regular season to its conclusion, and while the Australian Baseball League’s Championship Series pairing had been foreshadowed a week earlier, the final answers were only locked in after a tense, rain-affected weekend.

Sydney became the first team to clinch a spot in the Championship Series, navigating a road trip to Perth to take three of four. At the same time, Adelaide powered through Brisbane with a matching 3–1 series win, dragging themselves back to .500 and keeping their momentum in the battle for second.
