How Long Has Becky Lynch Been the WWE RAW Champion? Update

She became the first SuperGirls champion in June of 2005 and was slowly building her career. Unfortunately, in September of 2006 she suffered a head injury that kept her away from the sport for a long time. Towards the end of 2012, she returned and managed to nab a developmental contract with the WWE, and in 2013, went on over to NXT. 

After honing her skills and garnering fan support on the black and yellow brand, she then transitioned to the “main” roster in July of 2015.
