FactorThis fixture
Ballpark weatherWind and temperature at the park move run totals, but our ballpark weather module is pending a file-to-table persistence job.
Availability27 listed out or questionable (see Who's out above)

General rule: wind blowing out and warm air help the ball carry (more runs and home runs), while wind in and cold air suppress scoring; the starting pitchers listed above are the single biggest driver of the run total.
