Here’s a way to visualize a pitcher’s season using Bill James’ Game Score stat. I found that shapes were more revealing than a simple line graph and I was able to spot patterns more easily. Here are a few pitchers from 2010:
Roy Halladay: I was struck by the weirdly repeatable pattern he had in the first half of the season. Maybe he’s some sort of a cyborg or robot and trying to cover it up with intentional inconsistency.
Kevin Millwood: He faded in mid-summer, then career survival instincts seemed to kick in (or an urgent call from his agent).
Mat Latos: He had an amazing stretch of pitching, book-ended by two hideous starts. The Padres sure could have used “May, June, July, or August Latos” during their rough home stretch.
