Finally, the Cosa Nostra Donnas defeated the Texas Rollergirls 178-100 to claim the 2009 WFTDA championship at the end of an undefeated season.

[16] In 2012, Oly won their third Western Regional title in four years by defeating Denver Roller Dolls 168-161.

In 2014, Oly met their gameplay requirements (including reaching their required fourth sanctioned game on the final day of June), but when it turned out that the Division 1 Playoff they would be sent to was rescheduled to a weekend when USARS was holding their national championship, Oly declined their invitation to WFTDA Playoffs, as they couldn't field teams for both tournaments simultaneously, and elected for the USARS tournament, as it allowed for junior-aged skaters to play.

[21] While Oly was ranked within Division 1 territory for the 2015 cycle, again they did not meet gameplay requirements and were not eligible for that year's Playoffs.

Oly won the inaugural USARS National Championship by defeating San Diego Roller Derby 181-35 to claim the first Seltzer Cup.
