Suspended MLB pitcher Felipe Vazquez -- who's already behind bars and facing more than 20 felonies in a child sex case -- has been hit with a new child porn charge in St. Louis, according to reports.
Remember, 28-year-old Vazquez was arrested back in September for allegedly sexually assaulting a 13-year-old girl in 2017 ... and was also charged with sending nude pictures and videos of himself to the victim.
In docs, obtained by the Trib, Vazquez was charged with a count of "furnishing pornographic materials to a juvenile" in February ... a Class A misdemeanor.
According to the docs, the act allegedly went down from Vazquez's hotel room on July 16 ... when he sent nudes and a video of himself masturbating to a 15-year-old girl.
Worth noting ... the Pirates beat the Cardinals 3-1 that same day, and Vazquez recorded the save for Pittsburgh.
The Westmoreland County, PA Assistant DA told the Trib he believes the minor is the same girl at the center of Vazquez's other charges.
Vazquez has been behind bars since September without bond ... and his next hearing is slated for June 23.
