What are MLB prop edges?

An MLB prop edge is the gap between the Malter Analytics model's probability that a player beats a prop line (home runs, hits, total bases, RBI, hits+runs+RBI, runs scored, walks, strikeouts, or hits allowed) and the probability implied by the sportsbook. A positive edge on the Over means the model thinks the Over is +EV; a negative edge means the Under is +EV.

Q: What is a First Plate Appearance prediction?

The First Plate Appearance panel shows the Malter Analytics model's predicted probability that a batter's first at-bat today ends in an out, walk, HBP, single, extra-base hit, or home run. Useful for first-inning and first-at-bat prop markets where edges vanish once play starts.

Q: Why don't I see every MLB player on this page?

Only players with at least one live Over/Under line posted by a sportsbook are included — without a book line there's nothing for the model to produce an edge against. Batters with fewer than 30 career plate appearances and pitchers with fewer than 5 career starts are also excluded because the model doesn't yet have reliable personal data for them.

Where the Malter Analytics model disagrees with the sportsbook. Every prop below is an over/under pick sorted by edge. Green = Over has positive EV · Red = Under has positive EV · Gray = model agrees with the book. Not gambling advice.

To keep the model's edges reliable, we only include batters with at least 30 career plate appearances and pitchers with at least 5 career starts. Players with less history don't have enough data for the model yet and are excluded.

About MLB Prop Edges

MLB Prop Edges compares the Malter Analytics prop model against live DraftKings, ESPN BET, William Hill, BetRivers, and FanDuel Over/Under lines for every player prop market — home runs, hits, total bases, RBI, hits + runs + RBI, runs scored, walks, pitcher strikeouts, and pitcher hits allowed. The gap between the model's probability and the sportsbook's is the edge, and rows are sorted by edge so the biggest +EV picks of the day surface first.

Each batter on the page also has a First Plate Appearance prediction, showing the model's probability that their first at-bat today ends in an out, walk, HBP, single, extra-base hit, or home run. Useful for first-inning and first-at-bat prop markets where edges vanish quickly once play starts.
