I got a request for Norichika Aoki's graph, so here it is.
Also, I should mention that the last graph I posted for Kenta Kurihara contained a fairly big error on my end... Instead of grabbing the values for cumulative OPS, I think I grabbed the values for cumulative AVG -- this was the reason why his OPS was so low. The graph has since been updated. My apologies if it caused any confusion.
And as always, let me know if there are any specific players you'd like to see. As a heads up, I plan on doing Takeya Nakamura next.
