The Recipe for the Red Sox’ Secret Sauce
Every plate appearance, every run, and every win is magnified in the postseason. The Red Sox came to bat more than 6,000 times, scored nearly 900 runs, and won 108 games during the regular season. In the playoffs, it’s been roughly 400 plate appearances, 68 runs, and nine wins so far. Because it is the playoffs, and because it is fun and important and special, when players and teams do something out of the ordinary, it stands out and deserves greater discussion. This postseason, the Red Sox have scored more than half their runs with two outs and, with two outs and runners in scoring position, are hitting like J.D. Martinez in the middle of a hot streak. That’s amazing, and it is great for the Red Sox, but we should be a little leery of trying to extract some sort of design or strategy from this great run.
Over at the Athletic, Jayson Stark has some of the amazing numbers the Red Sox have put up this postseason, including how they’ve scored 36 of their 68 runs with two outs. Teams usually score about 37% of their runs with two outs, so an increase by close to 50% is impressive. To try and determine how unusual of an occurrence this is, I ran a simple test, looking at the percentage of team runs scored with two outs from August 1 to August 13 of this year, roughly approximating the number of games the Red Sox play in October. During that one random stretch, no team was as high as 53% like the Red Sox arecurrently, but four teams were above 45%, with the Nationals at 48% to top the league. This is just one random stretch, but with a standard deviation of seven percentage points, what the Red Sox are doing puts them in the top 5%.
Then, for the same dates, I looked at team stats for runners in scoring position with two outs. Nobody ran numbers quite like the current Red Sox streak, with a wRC+ in the 220s, but there were two teams with at least a 190 wRC+ in the sample. One of those teams was the Braves. The other was these Boston Red Sox. So while what the Red Sox are doing is unusual, it also isn’t something that is impossible — and, indeed, the Red Sox seemed to do it earlier this season in early August.
