Correlation is not causation.
As I mentioned before, what also happened from 1993-2007? Four expansion clubs were added, including one at an altitude that saw many home runs hit in its park.
Thirteen* new ballparks were opened, a rate of park replacement unprecedented in major league history (the figure goes to fifteen parks if you include the new fields built in Chicago and Baltimore just prior to 1993). How have you controlled for these occurrences in your statistical "analysis"? What about other possibilities, such as changes to the ball? (MLB typically denies it makes any changes to the ball, but it is a possible influence that can't be entirely discounted.)
*Does not include the parks built for the expansion teams.
