Nothing in the rule states it is an automatic ejection, and it even states that the act must be done in disgust of an umpires call and it must be flagrant to be an ejection.... I would hope you would not base the throwing of the ball as your sole proof of either of these stipulations. Even at the collegiate level I would not right paper on this unless he added something like "I honestly think you blew that call Mr. Umpire", and then bounced the ball up my skirt......
