Yeah, sorry, JK never left Innova. She is not listed on Prodigy's site on their team page and she is listed on Innova's. Also, I am positive I never heard about her leaving when Prodigy started and created the big shakeup.
She actually doesn't play many tournaments anymore. If you look at her PDGA page, she played 3 this year and 3 last year, but no majors or NT events. Before that, she played nothing back until 2011 and from 2011 back it looks like she sporadically played 1 or 2 tournaments every year or 2. I suspect her name was probably taken off the champion Valk when she stopped competing full time.
