Shinya Kido and Yuki Spencer
Andre is the only person who has been mentioned in this thread who I would consider even close to a yoyo professional.
John Higby.
1 - Grzegorz Piwowarek aka Gaberus
2 - Plamek
3 - Jensen Kimmit
4 - Mateusz Ganc aka Gacek
PS. After PYYM’s with this my top “4” I’v changed my mind, about the sequence, but the names are same 
Greetings Gaberus, Plamek, Jensen and Gacek!!! :*
Mark Montgomery, no contest.
Samad is cool, but mostly because he’s awesome YYE brotha!!!
Doc Pop by far!
If you want to talk about the true form of professional, meaning getting paid just to yoyo, that would be The Higby family!
If you are talking about sponsored players in general then I’d have to say either Adam Brewster (style and innovation points) and Seth Peterson (same reason).
A close second is two people. Andre for making this stuff look too easy.
Miguel Correa for just being and awesome guy and yoyoer.
