Platoon Advantage
Batters historically hit better against opposite-hand pitchers
Left-handed batters see the ball better against right-handed pitchers. Breaking balls move toward the bat.
Right-handed batters hit lefties well. Fewer LHP in MLB means less familiarity for batters, but the platoon edge still holds.
Switch hitters bat from both sides, neutralizing any platoon advantage. Focus on pitcher quality and other factors.

Handedness Impact on Betting
When to bet on the lineup with platoon advantage
LHP Starting vs RH-Heavy Lineup
Right-handed lineups historically crush left-handed pitching. The opposite-hand advantage compounds across 6-7 right-handed bats in the lineup.
RHP with Elite Stuff vs Same-Hand Heavy Lineup
When a dominant right-hander faces a predominantly right-handed lineup, same-hand strikeout rates spike. Breaking balls move away from same-side batters.
Switch-Hitter Heavy Lineup
Lineups with multiple switch hitters neutralize the platoon advantage entirely. The handedness matchup becomes a non-factor.
Bullpen Handedness Mismatch
Late-game bullpen matchups can swing outcomes. A lefty-heavy bullpen facing right-handed pinch hitters in the 7th-9th creates platoon edges.

Pitcher Archetypes
Profile-based betting angles and risk factors
The Strikeout Artist
K/9 > 10, BB/9 > 3.5High ceiling, high floor. These power arms dominate when the stuff is working but can implode when they lose command. Walk rates keep pitch counts high.
The Command Pitcher
K/9 < 8, BB/9 < 2.5Induces weak contact and goes deep in games. Low walk rates keep runners off base. Efficiency is the name of the game with these pitchers.
The Ground Ball Machine
GB% > 50%Park dimensions matter less with ground ball pitchers. They keep the ball on the ground and let the defense work. Sinkers and two-seamers are the weapons.
The Fly Ball Pitcher
FB% > 40%VERY park-dependent. Fly ball pitchers live and die by the ballpark. Coors Field and Great American Ballpark are nightmares; Oracle Park is a haven.

A step-by-step process for matchup-based edges
Matchup Edge Checklist
Work through each step before placing a matchup-based wager
Check starting pitcher handedness and splits
Look at the starter's platoon splits. How much worse do they perform against opposite-hand batters? Large splits = larger platoon edge.
Cross-reference with lineup composition (% RHB vs LHB)
Count the number of right-handed, left-handed, and switch hitters in the projected lineup. A lineup stacked against the pitcher's weakness amplifies the edge.
Layer park factors on top
Some parks suppress offense (Oracle, Dodger Stadium) while others inflate it (Coors, Great American). Park factor modifies the platoon edge.
Check weather (if open-air park)
Wind direction, temperature, and humidity all affect ball flight. Hot + wind blowing out = more offense. Cold + wind blowing in = more pitching.
Compare to market line for edge
After accounting for all factors, compare your projected total or side to the market line. If there is a meaningful gap, you have found an edge.
