The Boston Red Sox have scored 655 runs. That’s 5.5 per game which leads MLB. The second best offense, the New York Yankees, have scored 601, good for 5.18 per game. That puts the two teams on pace for 892 and 839 respectively. For Boston, that would be the most runs scored in a season since 2005 and would be an increase of 107 runs from 2017. The 2004 team scored 949 runs and in 2003 they finished with 961. But raw runs scored isn’t always the best way to look at an offense.
Offensive environments change from year to year which is why we have league and park adjusted offensive metrics like wRC+ and OPS+.
