The Run Differential Report

by Bill Chuck on September 13, 2013

Run differential is used frequently as the critical predictor of a team’s success.

While it is not foolproof, it is pretty close.

When you look at the run differential for the season, you will find that no team with a negative run differential has a winning record.

But, it’s the middle of the pack group that I find the most interesting

  • The Angels are 70-76 and have scored 664 runs and allowed 673, a negative nine differential
  • The Nationals are 77-69 and have scored 589 runs and allowed 581, a plus eight differential
  • The Diamondbacks are 73-72 and have scored 605 runs and allowed 611, a negative six differential
  • The Yankees are 79-68 and have scored 612 runs and allowed 612, totally even in runs
