Flat Track Stats flags several roller derby upsets in busy July slate
Bay State Brawlers' 212-143 win at Green Mountain was the week's biggest upset in a slate Flat Track Stats labeled fully played and hard to predict.
Bay State Brawlers’ 212-143 win at Green Mountain was the biggest upset on Flat Track Stats’ July 9-15 panel, even with a final margin that never looked like a coin flip. The same weekly view tracked eight sanctioned bouts on the July 11 slate and showed zero predictable bouts in its top-line summary, which is a sharp way to measure how unsettled the field has become.
The tightest finish came in Ithaca’s 140-137 escape over Boston Roller Derby: Boston C, a three-point result that stood out as the closest game on the board. Boston C entered that bout ranked 91st in NA Northeast, with Ithaca listed as the July 11 opponent, and the margin shows how little room there is for error when the teams are this close in the rankings. In sanctioned play, that matters because WFTDA only recognizes games that follow its sanctioning policies, so these results feed directly into the ranking picture instead of lingering as exhibition noise.
The rest of the slate mixed expected wins with a few results that pushed the model harder than the raw scores suggest. Akron, ranked 44th in NA Northeast, hammered ROCK 203-64. Mid-State protected home track against Marquette, winning 167-120, while Savannah fell 150-205 to LCHR Bruisin’ Betties and Memphis lost 113-163 to Twister City. Flat Track Stats’ upcoming-bouts view had already marked Marquette at Mid-State and Savannah at LCHR Bruisin’ Betties as the closest predictions, which fits a week where some games were closer on paper than on the scoreboard.
The ranking movement tells the real story. Flat Track Stats flagged gains for Akron and Bay State Brawlers and declines for Green Mountain and ROCK, so the July 11 results changed more than a set of scores. Bay State’s rise came against a Green Mountain team whose highest-ever regional ranking was 61st in September 2013, while Bay State’s best mark was 64th in June 2023 and Boston C’s peak was 71st in June 2025. That kind of history gives the July slate its edge: one busy week did not rewrite the sport, but it did show how fast sanctioned derby can punish a bad night and reward a sharp one.
