"Own goals" (kicking a ball into one's own net) are uncommon in soccer ("football") and ice hockey. Because this one occurs in a youth sporting event, it is just indescribably cute.
As a soccer referee, I had this happen twice in one game(U-8) by the same kid. I told him he should try throwing the ball out, and he said "Yeah, that might be better."
She actually got a high five for that! :-)
