Roger Clemens' 34-year-old son, Kory, has been arrested again for DWI, TMZ Sports has learned ... and the allegations against the MLB legend's kid are scary.
According to court documents, Kory was busted by the Houston Police Dept. in Texas at 2:22 AM on April 7 following a car accident.
In the docs, prosecutors allege Clemens struck another vehicle, which caused "heavy" front-end damage. They also say Kory was throwing up at the scene and was "unsteady on his feet." They added in the documents that he reeked of booze, had bloodshot eyes and slurred his speech .
