Champion Sports and Rookie of the Year

I haven't seen anywhere these two stories have been compared. I have wondered about it for awhile now. So I guess I will do it here.
Champion Sports #1 featured a story called "The Kid Who Beat The Oakland A's" It was published in 1973 by DC Comics. I am not sure who owned them at the time but a few years later they were owned by Warner Brothers and still are to this day.
The story centers around a high school student. He wants to be a sports writer and decides to try out for the high school baseball team. That way he will have real life experience. He is not very good until he hurts his arm and suddenly he is one of the most powerful pitchers around. He get signed by a new team called the Bulls . Like the title said he pitches against the then world champion team Oakland A's and they win. Later a car accident cause them to have to operate on him. The Dr. notices something is wrong with his arm during the operation and fixes it. After that the boy just has a normal pitching arm and has to quit baseball.

Now rookie of the year. The move was produced by 20th Century Fox in 1993. It centers around a boy who is maybe in the 8th or 9th grade. Loves baseball and hurts his arm while playing baseball with his firends. Suddenly when his arm heals he has one of the most powerful pitching arms around. He is signed by the Chicago Cubs. Later another accident happens to his arm and he now throws normal for a boy his age and has to quit baseball.

I am not a person who believes in alot of lawsuits. However, I have always wondered why there were none around this. There are alot of similar plotpoints in these two stories. Maybe it is because that Warner Brothers didn't own DC at the time. Couldn't DC have done it on their own? Who knows? This was just something that I had on my mind.
