Weather & injury impact for this fixture

Conditions · who's out · how it moves the number
For St. Louis Cardinals 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 23 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.
Availability23 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.

Jorge Polanco (SEA) Under 1.5 Singles (-385)

Odds available at draftkings at time of publishing

The bet on Jorge Polanco for Under 1.5 in the Batter Singles market is statistically sound. Over the last five games, Polanco's average for singles, both overall and at home, is less than 1 (0.4 and 0.8 respectively), well below the line of 1.5. His batting averages, both overall and against the opposition, are also below 1.5 (1 and 0.6 respectively), suggesting a lower likelihood of hitting more than one single. Despite Polanco's current hit streaks, the data suggests that his hits are not typically singles. Therefore, the under 1.5 bet is a good choice as Polanco's recent performance indicates he is unlikely to hit more than one single in the upcoming game.
