What’s New?

You’ll now see real-time weather data and Ballpark Factor ratings directly inside Outlier for every MLB game. These insights can give you an extra edge especially when betting on home run props.

1. MLB Weather

For each matchup we display:

  • Temperature & Conditions: Current game-time forecast including cloud cover and precipitation chance.

  • Wind Direction & Speed: See how wind may help or hurt hitters, whether it’s blowing out to the fences or holding balls in play.

  • Humidity & Dew Point: Subtle factors that can influence how the ball travels.

All weather info updates in real time so you can adjust your bets right up to first pitch.

Pro Tip: Use the Outlier web app (favored among power users) 🖥️

1) You can login here https://app.outlier.bet/login (do not click the AppStore button)

2) Make sure to use the same login method you signed up with (email, phone, AppleID, etc).

2. Ballpark Factor

Not all stadiums are created equal. Ballpark Factor measures how friendly each park is for hitters or pitchers:

  • Higher numbers favor batters (think more extra base hits and home runs).

  • Lower numbers favor pitchers (expect fewer balls leaving the yard).

For example, Coors Field ranks #1 with a 115 Ballpark Factor, meaning it historically produces significantly more offense than an average MLB park.

Why It Matters for Home Run Props

Combining weather conditions with Ballpark Factor can reveal prime spots for long balls:

  • A warm, humid night with a breeze blowing out in a hitter-friendly park? Home run chances may rise.

  • Cool, damp air with wind blowing in? It may be a night to fade those HR props.

How to Use It

When you’re viewing a player prop on web:

  1. Check the Weather panel on the right to see game-time conditions.

  2. Tap “Ballpark Factor” for a full league ranking and to quickly compare venues.

These two additions give you more context behind the numbers and help you make smarter MLB bets. Explore today’s games and see how weather and park effects could influence your picks.

Start using Weather + Ballpark Factor now and take your baseball analysis to the next level.
