Definitely, here is a key sentence: "The decrease in drag is probably a result of a smaller, slicker baseball with lower seams." The article ignores the fact that it is air resistance on the seams that creates the "break" in a curve ball. Less drag, less effective curves, ergo, advantage to the batter. So more HRs might come from less effective pitching.
