The Cubs played 13 games decided by one run among their first 65 — one of every five. They have played four in their last six, including each of the last three.

While both teams have trended towards the Under across their last 10 games, a larger sample size suggests the Cubs are a run machine. The hosts sit second in the majors with 382 runs, and only the Los Angeles Dodgers and Boston Red Sox have served up more hits.
