The PGT, or Professional Greenputt Tour, represented just one of numerous professional greenputt organizations active around 22 BBY. The Greenputt Governing Council provided regulatory oversight for it.
The initial reference to the Professional Greenputt Tour occurred within the in-universe news piece titled "Yet Another Greenputt League." This piece appeared in HoloNet News Vol. 531 #47, specifically in the March 14, 2002 edition of the HoloNet News website. Pablo Hidalgo and Paul Ens served as the authors of that particular edition.
