How we create and check guidesThe short answer
Starting pitchers strongly affect MLB moneylines and totals because they influence many early-game plate appearances. A confirmed starter change can move a price quickly.
Simple example
If an ace is scratched for a replacement starter, the opponent's price and game total may rise. The size depends on the replacement, bullpen, lineup, park, and weather.
Details that matter
- Strikeout, walk, and home-run rates.
- Pitch count, workload, and injury news.
- Handedness against the expected lineup.
- Bullpen quality and recent usage.
Not the whole game
A starter works only part of nine innings. Defense, offense, travel, weather, and relief pitching matter too. News can explain a move; it does not prove a price is valuable.
