Visualizing Game Score

You may have heard of Game Score, a Bill James stat that quantifies the quality of a pitcher’s start, incorporating a number of measures such as number of innings, runs allowed, strikeouts, hits, walks, and so on.  A score of 100 is about as good as it gets, and a 50 is about average.  Here are a few pitchers from 2010:

Is Andy Pettitte a Hall of Famer?

Hi there. I’m back after a prolonged offseason hibernation. Over the last several months there’s been a fair amount of the annual “Is he a Hall of Famer” debate. There’s the “the numbers tell me” argument, which tends to help players like Bert Blyleven. And there’s the “my eyes tell me” argument, which tends to favor players like Jack Morris. Here’s a fusion of the two, using our “eyes” to look at “the numbers” courtesy of Rankometer.

With Rankometer, we examine a pitcher’s career by visualizing how his WAR stacked up against his peers each season. Since a Hall of Famer should be performing at an elite level, we look at the top 30 starting pitchers in each season, since they would seemingly represent the “elite” (each team’s ace, the top 20 percent, however you want to look at it). So let’s take Rankometer for a spin and see what our eyes tell us.

Let’s first look at a first ballot Hall of Famer, Greg Maddux. What do my eyes tell me? He was the best among the best for a long stretch. Consistent dominance for an extended period of time. The big block of color says “Hall of Famer” to me.

Now let’s look at a borderline candidate, Mike Mussina. Rankometer reveals a lesser pitcher than Maddux, but still an elite pitcher for an extended period of time, with some off-years here and there. Hard to say with Mussina, but after looking at his Rankometer I am more of a believer.

Now, let’s look at Andy Pettitte. What do your eyes tell you when you look at his Rankometer? To me, the visual doesn’t come close to Mussina’s (let alone Maddux’s). I know we’re not considering his postseason resume, which this doesn’t capture (maybe a future revision could). But still, my eyes don’t tell me “Hall of Famer” when I look at this visual. What do you see?

Score Tracker compares the Giants and Rangers

Here’s a look at the Giants and Rangers, using Score Tracker to compare their wins and losses in the 2010 postseason. Like everything in Texas, the Rangers have done everything big, with only one game decided by 2 runs or less. In contrast, the Giants have been anything but Giant, taking more of a “conservationist” approach to their games. With the exception of their 6-1 loss and their 3-0 “blowout,” every game has been decided by 2 runs or less.


Here’s a look at the New York Yankees batting order, comparing regular season OPS with postseason OPS. Cano and Granderson have stepped up, while a parade of Yankees (led by A-Rod) has shrunk from the limelight.

Paintomatic looks at the Giants Starting Rotation

Here’s a look at the San Francisco Giants’ starting three for this series. It’s unclear why the Giants flipped Matt Cain and Jonathan Sanchez, but after looking at Paintomatic it does make some sense. For the most part, Tim Lincecum and Cain throw the same pitches, at roughly the same velocity and with similar frequency.
