It is *very* unlikely, unfortunately, you can hold the company responsible for a leisure event, even if it was "company sponsored."IF the ball game is actually part of your job--i.e. you are required to play softball--it's *possible* you may  have a worker's compensation claim. However, if it's not a required part of your job, then even if its sponsored by your employer, your injury there is not work related and worker's compensation would not be available.If you can't recover on the basis of worker's compensation, you could only recover compensation if you can show that the company or  other employees were at fault in some way. However, from what you write--you fell--it's difficult to see company fault in what happened.Also, when someone chooses to play a sport, they assume or accept the ordinary risks associated with that activity and usually can't recover for them. Fallling and getting an injury is an ordinary risk with playing softball.In short, it is doubtful that you can compel the company to pay for your non-working time caused by this injury.
