Welcome to First Inning Edge — Start Here šŸ”

Welcome to First Inning Edge


You're now inside the only coaching program built specifically around the MLB first-inning markets.


Here's what to do first:


---


Step 1: Complete the Course


Head to the Live Call Replay Vault tab and work through the course in order:


  1. Chapter 1: Model Foundations — Why the first inning, what markets you're betting, how to set up your data workflow

  2. Chapter 2: Starting Pitcher Split Analysis — The five core metrics, home/away splits, pitch mix

  3. Chapter 3: The Scoring Matrix — The full scoring framework, weighting variables, daily process

  4. Chapter 4: Live Call Replay Vault — Watch real games scored in real time

  5. Chapter 5: Advanced Application — Weather, park factors, bankroll management, the edge log


The course is designed to get you running the model within a week of joining.

Step 2: Check the Daily Analysis Feed


Every morning before first pitch (10 AM ET), the day's slate is scored and posted. You'll see:

  • Confirmed starters

  • Model scores for the day's card

  • NRFI / YRFI leans with line thresholds

  • Weather and park factor flags


Check this before you place any first-inning bets.


---


Step 3: Join the Members Chat


Introduce yourself in the Members Chat. Tell the group your betting background and what markets you've been focused on. This is an active community — bring data and you'll get data back.

Ground Rules


  1. The model is a tool. You own your own bets and bankroll decisions.

  2. Don't share member-only content publicly.

  3. Data over opinion. Always.


Welcome. Let's work.

We built a first-inning scoring model. Here's how it works.

Most MLB bettors are focused on the wrong things — season ERAs, win-loss records, recent form. We built First Inning Edge to fix that.


The NRFI/YRFI markets are the most exploitable in baseball


The first inning is structurally different from every other inning:

  • Pitchers are cold. Command is lower, spin rates haven't stabilized.

  • Hitters have had all day to prep. They know what's coming.

  • The market is less efficient. Books price first-inning lines off overall pitcher data, not first-inning-specific splits.


That gap is where the edge lives.

What we do inside First Inning Edge


The Model — A five-pillar scoring system built on FI-ERA, xERA, Barrel%, BB%, K%, and situational adjustments for park factor, weather, and lineup construction. Every game gets a score from 0–100. The score tells you whether to bet NRFI, YRFI, or skip.


Daily Analysis Feed — Every morning before first pitch, the day's slate is scored and posted with leans and line thresholds.


Live Call Replay Vault — Weekly coaching calls are recorded and uploaded. Real games, real scores, real results.


Members Chat — Active community of bettors running the same model. Data, line shopping, and real-time updates.

Who this is for


Serious bettors who want a repeatable, data-driven approach to first-inning markets. Not picks. A model.
