What is the distraction doctrine and the limited duty rule; and how do they apply in cases involving spectator injuries at sports venues?

In evaluating the orange toss described above during the 7th inning, please read Coomer, Harting, and Jennings each of those cases involved injuries resulting from projectiles at baseball games. Assuming one of our fans was hit with an orange and injured during the orange toss, you need to determine whether precedent established in any of those cases would be persuasive in deciding a case against our organization. For each case, you will want to explain your analysis and conclusion I would recommend that for each case, you write a succinct statement of the rule established in the case to support your discussion/explanation; and explain why you have concluded that any or all of these cases would be helpful precedent for us to avoid liability; unhelpful precedent to avoid liability; or simply inapplicable to our scenario?
