I have not seen John Thurston lately, but in the past I have coached a team that played against him, as well saw him play at various AAU National Tournaments.
As a pitcher he seemed to have a bulldog type personality. My only concern he seemed to pitch too many innings when he was younger.
I know a couple of his summer coaches if you need further info. You can reach me via my e-mail at alm@mostvaluableplayer.biz if you want more.
Don't recognize the other kid. Sorry.
