Weather & availability impact for this fixture

Conditions · who's out · how it moves the number
For Chicago Cubs vs Seattle Mariners: Ballpark wind and temperature can swing the run total, though the live per-park feed isn't wired into this page yet, and 26 players are listed out or questionable across both sides.
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.
Availability26 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.

Ballpark weather module pending a file-to-table persistence job (owner). We won't show a wind/temperature number until it's persisted to the database.
