My co-blogger Caleb has an amazingly efficient way of doing complicated statistical analysis. He mentions them to me in an interesting way, then waits for me to do the analysis.
We were discussing his post on the Taco Bell offer to buy everyone in the country a taco if there is a stolen base in the World Series when he mentioned that there aren’t that many stolen bases and they might not have to give away the yummy tacos after all. After all, Taco Bell has done baseball promotions for the last five years, and no tacos have been given away yet. (The conditions have not been met.)
So what are the odds of a stolen base in the World Series? Well, thanks to ESPN’s wonderful Baseball Statistics Page we see that the American League teams have averaged 97 stolen bases this year to the National League’s 98. That’s 97 stolen bases on average for teams in the majors this year.
Of course a baseball game takes two teams to play so if we do some math on the 162 game season and add it up we get 1.19 stolen bases per game this year.
If we only consider the stolen bases of the two teams playing in the World Series (Sox,96; Rockies, 100) the stolen bases per game go up to 1.2 per game. The chances are excellent that we all get tacos.
We also mused about the halcyon days of our youth, when runners were faster, bolder, more honest, more charitable and all around better people. (Men always romanticize the baseball of their youth.) Were more bases stolen years ago?
Yes. In the last six years MLB teams have stolen an average of .55 bases per game. In the six years between 1985 and 1990 the average was .80 stolen bases per game. This is a very significant difference.
But what if we go back even further? Between 1935 and 1940 (there were only 16 teams playing 154 mobile games then) each team had an average of only .38 stolen bases per year.
What can we surmise about this? Maybe runners have slowed down in the last 20 years? Have catchers gotten more accurate at picking off runners? Maybe base running is no longer as important to the game as it once was? I don’t know. But these are the questions baseball fans can argue over, and that’s one of the reasons we love the game.
So will we get our tacos this year? Yes. Absolutely. The chances of NOT having a stolen base are incredibly small. How many people will redeem them, and what will this cost Taco Bell? Excellent questions. Luckily for me Darren Rovell has already answered it for me.
