How to Bet MLB Player Props: A Beginner’s Guide

MLB player props are one of the fastest-growing markets in baseball betting—and for good reason. They offer action on individual player performances, giving you dozens of ways to find value beyond just picking who wins.

In this guide, we’ll explain how to bet MLB player props, how each prop type works, and how Rithmm helps you make smarter decisions using AI-driven projections.

Whether you’re betting strikeouts, total bases, or home runs, this post will show you how to level up your prop game with real data.

What Are MLB Player Props?

MLB player props are bets on the individual performance of a hitter or pitcher during a game.

Instead of betting on the outcome of the game, you’re focused on specific stat lines like:

• Will Shohei Ohtani hit a home run?
• Can Pablo López record over 6.5 strikeouts?
• Will Bryce Harper have more than 1.5 total bases?

Player props are especially popular in PrizePicks, parlays, and same-game bet slips—and Rithmm provides AI-powered projections for every major prop type.

What Are MLB Team Props?

Team props involve bets on how a specific team performs—rather than a player.

Examples include:

• Team to score first
• Total team runs (Over/Under)
• First team to 3 runs

Example: Bet on the Dodgers to score over 4.5 runs in a game.

Team props are often influenced by lineup strength, bullpen fatigue, and starting pitching—all factors Rithmm’s models help you evaluate through its full-game projections.

What Are MLB Game Props?

Game props involve outcomes within the game that don’t rely on who wins.

Popular game props include:

• NRFI (No Run First Inning)
• First 5 Innings Total
• Total Hits, Runs, and Errors
• Will the game go to extra innings?

Example: Bet on NRFI (No Run First Inning) in a matchup with two elite starting pitchers.

While Rithmm’s AI MLB Picks are focused on full-game outcomes, its models help identify games with early scoring risk (or lack thereof)—perfect for NRFI bettors.

How Do MLB Player Props Work?

Most MLB player props are set as Over/Under bets on a projected stat line. You’re betting whether the player will go over or under that number.

Let’s break down a few examples using actual prop types you’ll find in the Rithmm app:

Batter Props

Hits (H)

Will a player record at least one hit?
Example: Over/Under 0.5 hits for Julio Rodríguez.

Total Bases

All bases from hits count (1B = 1, 2B = 2, etc.). Walks and HBPs don’t count.
Example: Over 1.5 total bases = two singles or one double.

Doubles, Triples, Home Runs

These are specific: you’re betting on a player to hit at least one of that type.
Example: Over 0.5 home runs for Matt Olson.

Walks (BB)

How many times will a batter draw a walk? Great for plate-discipline specialists.
Example: Over 0.5 walks for Juan Soto.

Runs, RBIs, Stolen Bases

These stat-based props vary in volatility, but can provide strong value—especially in soft matchups or favorable ballparks.

Example: Over 1.5 RBIs for Aaron Judge vs a weak bullpen.

Pitcher Props

Strikeouts (Ks)

One of the most popular prop types in MLB betting.
Example: Over/Under 6.5 strikeouts for Spencer Strider.

Total Outs

Pitcher must record at least “X” number of outs (each inning = 3 outs).
Example: Over 17.5 outs = pitcher must go at least 6 full innings.

Walks, Earned Runs

These props are great for fading pitchers in tough matchups.

Example: Over 2.5 earned runs allowed vs a top-5 offense.

Rithmm gives you win probabilities and stat projections for every major prop—so you don’t have to guess which line offers the most value.

How to Pick the Best MLB Prop Bets

So what makes a prop worth betting?

Here are some quick tips for spotting high-value props:

✅ Look for mispriced lines — Props that deviate significantly from Rithmm’s projections
✅ Focus on matchup edges — Like lefty/righty splits or bullpen fatigue
✅ Use volume-based props — High-floor props like hits, walks, or outs can offer more predictability
✅ Track performance by ballpark — Some stadiums (like Coors Field) are prop goldmines
✅ Use AI models to filter noise — Rithmm simulates thousands of matchups to give you a sharper angle
