So likely meets  by the letter by the single race appearance.  However, with Xfinity being 2nd tier and a lot of auto sports being ride-buy situations, one could argue Xfinity is not fully professional (while one could even make that argument for F1 and Indycar (and even Sprint Cup Series), at least those are top tier racing series).  Besides that, of the sources provided, few if any actually qualify for GNG, mostly because they are not independent.  Most are press releases, from what appear to be sponsors, or what appear to be the series themselves.  Even the ones that don't fall under those issues, they look to be very obscure that are either blogs or look to have little editorial review - and of those, most are one sentence passing mentions (e.g., one article just has a bullet saying its was his debut).  I commonly follow , but this is a bridge too far even for me.  Considering this is an active racer, we should be able to find sources online if they are out there.  I say delete unless someone can show the sources
