A LOBster in Every Pot

Look, I know that isn’t the line. It’s a chicken in every pot. But I came up with a good lobster pun last week, and I’m writing more about the ins and outs of teams driving home runners from third base, so I decided to go back to the well. You’ll just have to live with it; I’m the one driving the boat here, and as it turns out, it’s a lobster boat.
With the puns are now settled, let’s get down to business. Last week, I chopped up the 2023 season into halves to see how well various statistical indicators correlated with a team’s future ability to cash in their runners. As a recap, strikeout rate had a fairly strong correlation, and not much else did. Quite frankly, though, I wasn’t particularly convinced by that. There just wasn’t enough data. With only 30 observations, it’s too easy for one team to skew things, or at least that’s how it feels in my head.
There’s an easy solution: more data. So I used the same split-half methodology from last week and started chopping past seasons in two. More specifically, I picked the years from 2012-22, excluding the shortened 2020 season. In each case, I followed the same procedure: I split the season in two and noted each team’s offensive statistics in the first half. Then I looked at how efficient each team was at scoring when a runner reached third with less than two outs. I got a much bigger sample this time; 300 observations, which makes it a lot harder for a single outlier to mess things up. Read the rest of this entry »
