MLB Betting Markets & Player Props: The Complete SportsGameOdds API Coverage Guide

If you're building a sportsbook, an odds-comparison site, a props research tool, or a fantasy app, your MLB coverage has to go deep. Baseball is uniquely granular and bettors don't just want the moneyline and the run total, they want first-five-innings lines, individual inning markets, strikeout props for a specific pitcher, and total-bases props for a specific hitter, all priced across the books they actually use.

The SportsGameOdds API delivers that depth. Our MLB coverage spans 369 individual market entries across 142 distinct market types, from full-game lines down to eighth-inning run totals. This guide walks through the complete catalog, how markets are structured, and which bookmakers price each one.

Quick Overview: MLB Market Coverage at a Glance

Before the full breakdown, here's how MLB coverage maps across categories, with representative markets and the kinds of sportsbooks that price them.

Note: Sportsbook availability varies by individual market. Core game lines (moneyline, run line, total) are carried by 80+ books, while niche props and deep inning markets may be limited to specialist books like Pinnacle, PrizePicks, or Underdog. Every market below lists its exact bookmaker set.

How SportsGameOdds Market IDs Work

Every market in the API is identified by a structured oddID that encodes everything about the bet. Once you understand the pattern, the entire catalog becomes self-documenting.

The format follows this structure:

{statEntity}-{participant}-{period}-{betType}-{side}

For example:

pitching_strikeouts-PLAYER_ID-game-ou-over

Breaking that down:

• pitching_strikeouts — the stat being bet on
• PLAYER_ID — the participant (a specific player, or away/home/all for team and game markets)
• game — the period (game, 1h, reg, 1ix3/1ix5/1ix7 for first-3/5/7 innings, or 1i–9i for individual innings)
• ou — the bet type (ou = over/under, ml = moneyline, sp = spread, yn = yes/no, eo = even/odd, ml3way = 3-way moneyline)
• over — the side of the bet

Baseball's period codes are worth calling out, since they're what make deep MLB coverage possible: 1ix5 is the popular "first five innings" (F5) line, 1ix3 and 1ix7 cover the first three and seven innings, and 1i through 9i address each individual inning. This consistent structure means you can construct, parse, and filter markets programmatically without hardcoding thousands of strings.

Batting Player Props

Batting props are among the most-traded markets in baseball, and coverage is deep. The headline markets — hits, home runs, total bases, and RBIs — carry the widest bookmaker support, often 45+ books, and most also come in an "Any / Yes-No" variant alongside the Over/Under line.

• Hits (batting_hits-PLAYER_ID-game-ou-over / -under) — 45+ books, plus an Any Hits Yes/No variant (batting_hits-PLAYER_ID-game-yn-yes)

• Total Bases (batting_totalBases-PLAYER_ID-game-ou-over / -under) — 45+ books, plus Yes/No
• Runs Batted In (batting_RBI-PLAYER_ID-game-ou-over / -under) — plus RBI Yes/No
• Hits + Runs + RBIs (batting_hits+runs+rbi-PLAYER_ID-game-ou-over / -under) — the popular combined "H+R+RBI" prop, plus a Yes/No variant
• Singles (batting_singles-PLAYER_ID-game-ou-over / -under)
• Doubles (batting_doubles-PLAYER_ID-game-ou-over / -under)
• Triples (batting_triples-PLAYER_ID-game-ou-over / -under)
• Stolen Bases (batting_stolenBases-PLAYER_ID-game-ou-over / -under)
• Walks (batting_basesOnBalls-PLAYER_ID-game-ou-over / -under)

Are live MLB odds available?

Yes. In addition to pre-game markets, the API provides live in-game odds, including individual inning markets (1st through 9th), first-five-innings lines, and per-inning run totals — ideal for live betting products. For real-time updates during games, see the Live Odds API documentation. (Building for other sports too? See our NFL Odds API live football markets.)

Can I compare bookmaker odds?

Absolutely — odds comparison is a core use case. Every market returns prices from all supporting bookmakers under a single consistent oddID, so lining up the best available number across DraftKings, FanDuel, BetMGM, Caesars, Pinnacle, and dozens of others is straightforward. This makes the API well suited to odds-comparison sites, line-shopping tools, and arbitrage detection.

Does the API cover first-five-innings (F5) and individual inning markets?

Yes, and this is one of the strengths of our MLB coverage. First-three (F3), first-five (F5), and first-seven (F7) innings markets are supported across moneyline, run line, total, and 3-way. Individual innings from the 1st through the 8th carry moneyline, spread, total, and 3-way markets, plus "any runs" Yes/No and team run totals, with per-inning team run totals extending through the 9th.

How are markets identified in the API?

Every market uses a structured oddID in the format {statEntity}-{participant}-{period}-{betType}-{side} — for example, pitching_strikeouts-PLAYER_ID-game-ou-over. Baseball-specific period codes include 1ix5 for first-five-innings and 1i–9i for individual innings. This consistent pattern lets you construct, filter, and parse markets programmatically rather than hardcoding individual strings.
