Ellen, the owner of a baseball park, is under a duty to the entering public to provide a reasonably sufficient number of screened seats to protect those who desire such protection against the risk of being hit by batted balls. Ellen fails to do so.

a. Frank, a customer entering the park, is unable to find a screened seat and, although fully aware of the risk, sits in an unscreened seat. Frank is struck and injured by a batted ball. Is Ellen liable? Explain.

b. Gretchen, Frank’s wife, has just arrived from Germany and is viewing baseball for the first time. Without asking any questions, she follows Frank to a seat. After the batted ball hits Frank, it caroms into Gretchen, injuring her. Is Ellen liable to Gretchen? Explain.
