Why do righthanded pitchers generally throw harder than lefthanded pitchers?
Not sure that this is true, it may just seem that way because there are more right handed pitchers than lefties. There has surely been a lot of hard throwing lefthanders; Herb Score, Sandy Koufax and Steve Carlton are three oldtimers than come quickly to mind. There is also an old baseball adage that a lefthander cannot throw a straight ball, but I don't think there is any physical evidence to prove that. There is no physiological basis to the statement that right handers throw harder than left handers.
