Crunching MLB Prop Bets: A Guide to Computing Base-Out Runs Saved (RE24)

Baseball is a gold mine for statistics enthusiasts and sports bettors alike, and Major League Baseball (MLB) prop bets have exploded in popularity in recent years. One statistic that can offer bettors an edge is the Base-Out Runs Saved (RE24). Let’s delve into how to compute RE24 and how it can assist you in maximizing your MLB prop bets.

The Essence of RE24

The RE24, which stands for “Run Expectancy based on 24 base-out states”, is a Sabermetric statistic designed to measure a player’s contribution to their team’s scoring capabilities. This statistic considers the 24 possible combinations of runners on base (empty, 1st, 2nd, 3rd, 1st/2nd, 1st/3rd, 2nd/3rd, or loaded) and outs in an inning (0, 1, or 2), and calculates the expected runs that would score in each situation.

Computing RE24: A Step-by-Step Process

Calculating RE24 might seem like a complex process, but once you understand the underlying principles, it becomes a relatively straightforward task.

  1. Calculate the Run Expectancy Matrix: Before calculating RE24, you must first compute the Run Expectancy Matrix. This matrix uses historical data to show the average number of runs that are expected to score in each of the 24 base-out states. The MLB provides this data annually, which can be used for calculations.
  2. Compute Run Expectancy Before and After a Plate Appearance: To calculate RE24 for a particular plate appearance, you need to know the run expectancy before and after the plate appearance. This is determined by looking at the corresponding entries in the Run Expectancy Matrix for the base-out states before and after the plate appearance.
  3. Subtract and Add Runs: Subtract the run expectancy before the plate appearance from the run expectancy after the plate appearance, then add the actual runs scored during the plate appearance. This final result is the RE24 for that particular plate appearance.

To compute a player’s RE24 for a season or a series of games, you simply sum up the RE24s for each of his plate appearances.

Harnessing RE24 for MLB Prop Bets

Utilizing RE24 in your MLB prop bets strategy can prove to be highly beneficial. RE24 provides a comprehensive evaluation of a player’s ability to contribute to scoring opportunities, thus giving you a clear understanding of a player’s value. For instance, a player with a high RE24 is likely to be successful in scoring situations, which can inform prop bets related to player performance.

In the same vein, understanding a team’s cumulative RE24 can provide insights into their offensive efficiency, aiding in game-specific prop bets. If a team consistently records high RE24 values, it’s a strong indication they capitalize effectively on their scoring opportunities. Betting on prop bets such as ‘total runs scored’ in these scenarios could potentially yield fruitful returns.

Moreover, RE24 can provide insight into a pitcher’s ability to prevent scoring situations. A pitcher with a negative RE24 is effective at minimizing opponents’ scoring opportunities, making them a key consideration for ‘total runs allowed’ prop bets.

In summary, the RE24 statistic serves as a powerful tool in the arsenal of a savvy MLB prop bettor. By incorporating RE24 into your betting strategy, you could

gain a significant edge in understanding player and team performance, helping you to make more informed and potentially profitable MLB prop bets. Be mindful that while RE24 is a powerful tool, betting always comes with risks and should be approached responsibly.
