The daughter of ex-NBA player Corey Benjamin was involved in another on-court fight just weeks before her viral sucker punch ... new video, obtained by TMZ Sports, shows.
The violent altercation went down in mid-September in Del Amo, Calif. -- just two months before she sucker punched a girl during a youth basketball game near Anaheim last weekend.
In the footage, you can see the teenager was jockeying with another girl to try to gain position inside the key ... when she suddenly snapped.
Video shows Benjamin's daughter threw several punches at the girl -- before sprinting toward another girl on the court and throwing even more haymakers.
