Gut feel is how you lose money on MLB props. The pitcher "looks hittable," the batter's "been hot"—that kind of thinking gets you killed by variance. Our Best Bats dashboard replaces vibes with an 8-factor composite score that grades every hitter-pitcher matchup daily.

Here's what it measures, why it works, and how to use it.

## What It Actually Does

Every morning, the model evaluates each expected starter against their opposing pitcher across eight weighted factors. Each batter gets a composite score from 0 to 100, then gets slotted into a tier:

- **Elite (70+):** Strong confidence across multiple factors. These are the top plays.
- **Strong (60-69):** Clear edges in 2-3 factors.
- **Solid (50-59):** Slight edge. Worth considering in parlays.
- **Neutral (under 50):** No clear edge. Pass.

We track five prop types: hits, home runs, total bases, RBI, and strikeouts.

## The 8 Factors

**Opposing Pitcher Quality (22%)** — The heaviest weight, and the most predictive MLB factor. We evaluate ERA, WHIP, K/9, and days rest. A struggling pitcher with a 5.00+ ERA and 1.40+ WHIP facing a competent hitter creates a strong over signal.

**Recent Form (20%)** — Rolling 7-game weighted average using exponential moving average. Recent performance matters more than early-season numbers—that's why we weight it with alpha=0.70.

**Season Average vs. Line (16%)** — How the player's season average compares to today's posted line. A hitter averaging 1.2 hits per game against a line of 0.5 gets a strong positive signal.

**Platoon/Handedness Split (15%)** — A lefty batter with a 135 wRC+ versus RHP facing a right-handed pitcher gets a meaningful boost. Platoon advantage is one of baseball's most reliable edges.

**Ballpark Factor (11%)** — Coors gives hitters a 20% boost. Petco suppresses by 8%. We adjust for altitude, dimensions, and historical park factors.

**Weather & Wind (11%)** — Wind blowing out equals hitter-friendly. Wind blowing in equals pitcher-friendly. Temperature extremes affect ball flight.

**Lineup Position (3%)** — Batting 1st or 2nd means roughly 4.5 expected ABs versus 3.5 for the 8-9 spots. More opportunities, higher probability.

**Game Environment (1%)** — Total runs expected in the game. High-scoring environments (O/U over 9.5) favor hitter props.

## A Real Example

Take Juan Soto (LHB) versus a RHP with a 5.80 ERA and 1.45 WHIP at Coors Field, 15 mph wind blowing out.

Every factor fires: recent form (8-for-20 last 7 games), season average clearing the line, bad opposing pitcher, favorable platoon split (142 wRC+ vs. RHP), Coors, wind out, batting second, 11.5 O/U.

Composite score: 84. Elite. That's hits over all day.

Now consider the same hitter against a 2.90 ERA righty at Petco with wind blowing in. Half the factors flip. The model catches what your gut won't.

## Why Composite Scoring Beats Single Metrics

Every individual metric has blind spots. A great matchup on paper gets torpedoed by bad weather. A struggling pitcher faces a hitter in a cold platoon split. Park factors suppress what looks like a juicy line.

The composite approach doesn't care about any single factor. It cares about convergence—when multiple independent signals point the same direction. An Elite pick at 75 means five or six factors are all saying "yes." That's where the real edge lives.

Our nightly backtest validates this daily. In the 2025 season, Elite picks (70+) hit at 62.3% across hits, total bases, and RBI props. The system auto-adjusts weights when performance drifts.

## How to Use the Dashboard

Open [Best Bats](/mlb/best-bats). Filter by prop type—hits, HR, total bases, RBI, or strikeouts. Focus on Elite and Strong tiers. Click any row to expand and see how each factor contributed. Green bars are positive signals, red bars are negative.

Check it daily—matchups change with every pitching rotation. Yesterday's Elite pick is today's neutral.
