Adabi, a foreign student in the United States accepted an invitation from his friend Daniel to attend a baseball game with the intention to learn new things as he is clueless about baseball. Daniel got him the seat which is the best in the field

During the game, a player, Biblon, got angry and quarrelled with the first base umpire called him "out". He threw his batting helmet to the ground. The helmet, made of a strong, hard plastic material, bounced on the ground and flew into the stands, striking Adabi on the side of the head, causing a serious injury. Adabi never saw the helmet coming towards him because he was eagerly looking around the stadium at the time rather than at the play on the field. As he was unfamiliar with the game of baseball, he did not know that objects occasionally fly into the stands during a baseball game.

What arguments would Adabi make in support of a claim of negligence, what defense(s) can reasonably be asserted, and who is likely to prevail in a lawsuit filed by:

1. Adabi against Biblon? Discuss.

2. Adabi against Daniel? Discuss.
