2006 Dust Devil

In Tucson, Arizona, over the weekend of February 24–26, 2006, Tucson Roller Derby hosted 20 WFTDA leagues from around the United States in a tournament.^[29]

Round-robin bouts were instituted to determine seeding for a single-elimination tournament. Four pools were created, titled Scorpion, Tarantula, Black Widow and Rattlesnake, with each pool consisting of 5 teams. On Friday, February 24, 2006, each team played four ten-minute bouts in each pool. Point differential was used to determine the ranking and placement of each team within its pool. With this information in hand, tournament officials selected the top three teams of each pool and seeded them according to the point differential of each team for the single-elimination tournament.

The single-elimination tournament started on Saturday, February 25, 2006 with 12 of the previous day's 20 teams. Scheduling of the bouts allowed for the top four seeded teams to receive a bye in the first round of play. Teams seeded 5 through 12 played in the first round. The winners of the first round of the single elimination tournament played the top four seeds in the second round. Bout winners advanced to the semi-finals and bout losers were eliminated.

On Sunday February 26, 2006, four teams (Texas Rollergirls Texecutioners, Tucson Roller Derby Saddletramps, Minnesota Rollergirls All-Stars and Arizona Roller Derby Tent City Terrors) played in the semi-final bouts. In the first bout, the Texecutioners defeated the Tent City Terrors in a full three-period bout, 114 to 81, sending the Texas to the championship bout and Arizona to the 3rd-place bout. A second full three-period semi-final bout was played between Tucson and the Minnesota Rollergirls. Tucson defeated Minnesota 136–75. This pitted the Tent City Terrors against Minnesota for the 3rd-place bout, and set the WFTDA National Championship Bout to be between Texas and Tucson. The 3rd-place bout was played out with the Tent City Terrors upsetting 3rd-seeded Minnesota 115–88. The Championship bout was finalized later in the evening, with the Texecutioners defeating the Saddletramps 129–96.

The tournament also saw the first collaboration between roller derby announcers. Following the event, announcer Bob Noxious founded "Voices of Reason", an announcers' association.^[2]

2007 Texas Shootout

On September 30, 2007, the Kansas City Roller Warriors beat^[30] the Rat City Rollergirls^[31] 89–85 in the final match of the Texas Shootout to become the first WFTDA National Champions.^[32] The Texas Rollergirls placed third.^[33] Eight teams competed in the tournament, four from the eastern regional division and four from the western regional division. These teams included Carolina Rollergirls (fourth place), Gotham Girls Roller Derby, Tucson Roller Derby, Detroit Derby Girls, and Windy City Rollers.^[34]

Several marketing materials as well as a statement from WFTDA President "Crackerjack" on page 5 of the program^[35] for this event confirms that at the time it was considered the "first WFTDA Championship Tournament."

2008 Northwest Knockdown

On November 16, 2008, the Gotham Girls Roller Derby (GGRD All-Stars) beat the Windy City Rollers 134–66 in the championship bout. The Philly Rollergirls (Liberty Belles) beat the Texas Rollergirls (Texecutioners) 114–95 in the consolation bout to take third place.^[36]

2009 Declaration of Derby

The Denver Roller Dolls pioneered the "slow derby" style of play, utilizing slow and stopped packs and backwards skating, which proved effective against most opposition, but unpopular with crowds. They were finally defeated 178–91 in the semi-finals by the Oly Rollers were regarded as a largely unknown force, although they had gone undefeated through the whole season. Rocky Mountain Rollergirls had unexpectedly sailed through their qualifying tournament, and beat Philly Rollergirls in an overtime jam in their quarter final, but they lost to defending champions Texas Rollergirls 139–82 in the semi-final, in a bout which saw Rocky skater DeRanged ejected from the tournament after apparently punching Angie-Christ from Texas.^[37]

Denver defeated Rocky 151–103 in the third place bout, greatly aided by forty-four points to nil scored in the later section of the first half. Oly dominated Texas in the championship bout, taking the title 178–100.^[37]

2010 Uproar on the Lakeshore

The final was particularly hard-fought. The Oly Rollers built up a half-time lead, 84 points to the Rocky Mountain Rollergirls' 49, principally due to Atomatrix's power jams. Although she ultimately scored 101 points for Oly, Rocky Mountain were able to fight back in the second half. With one jam remaining, Oly retained an eight-point lead, but, jamming for the third time in a row, Rocky Mountain's Frida Beater scored nine unopposed points before calling off the jam, to secure a win by a single point.^[38]
