Listed pitchers vs action in MLB betting
An action moneyline stands whoever starts. A listed-pitcher bet is refunded if the named starter doesn't take the mound. Books apply this differently, and a scratch can void one leg of a hedge.

In MLB betting, “action” means your bet stands no matter who starts on the mound; “listed pitcher” means it only has action if the named starter (or starters) actually starts, and is refunded otherwise. The US books we checked default moneylines to action and offer a listed-pitcher option. The rules for run lines, totals and pitcher props differ from book to book — and when the two legs of a hedge sit at books with different rules, a late scratch can void one leg and leave the other running.
What three books publish
FanDuel's Colorado house rules default every moneyline to Action — bets stand at the odds taken if the pitcher changes — and offer One Specified Pitcher (void if that pitcher doesn't start) and Both Specified Pitchers (void unless both listed starters start). Every other game market there is action. Caesars' rules say wagers stand regardless of a pitching change except in its Listed Pitcher vs Listed Pitcher moneyline market, which is void if either listed pitcher doesn't start. Circa Sports' Nevada rules let you list one or both pitchers on a full-game or first-five moneyline, where listed means the pitcher must throw his team's first pitch; and if Circa's posted starting pitcher changes, it refunds prior bets on the total, team totals, run line and their alternates, and re-prices action moneylines to reflect the actual starters. All three were read on September 27, 2026.
Pitcher props follow their own rule
Strikeout, outs and similar props are about one pitcher, so they are void if he doesn't pitch — the definition varies. FanDuel voids pitcher markets if the listed pitcher doesn't start. Caesars requires the pitcher to throw his team's first pitch. FanDuel's strikeout props also stand if the opposing listed pitcher is scratched, even though the matchup has changed.
Why anyone lists a pitcher
A moneyline is priced around the two starters. If an ace is scratched for a spot starter an hour before first pitch, the fair price can move a long way, and an action bet keeps the old price. Listing protects you from betting one matchup and getting another. The cost is that a listed-pitcher option may not be offered on every market or at every book, and you give up the rare case where the change helps you.
- Circa: Team A −1.5 at +150, $100
- decimal 2.50
- FanDuel: Team B +1.5 at −130, $141.30
- decimal 1.769
- A covers: +$150 − $141.30
- +$8.70
- B covers: +$108.70 − $100
- +$8.70
- Scratch: Circa refunds the run line
- $0
- FanDuel's run line stands: B covers / A covers
- +$108.70 / −$141.30
Illustration built on the two books' published rules. The planned +$8.70 either way becomes a one-sided $141.30 bet at −130 on a game whose pitching matchup just changed.
- Book 1: Team A ML at +120, both pitchers listed, $100
- decimal 2.20
- Book 2: Team B ML at −130 (action), $124.35
- decimal 1.769
- Either team wins, as planned
- −$4.35 (a qualifying-bet style loss)
- Scratch: Book 1's listed bet is refunded
- $0
- Book 2 stands: B wins / A wins
- +$95.65 / −$124.35
Illustration. The same pair placed as action on both sides would have stayed matched: both bets stand at their original prices.
Matching the rules on both legs
- 1Use the same setting at both books: action on both, or the same listed pitchers on both. Action on both is the simplest pair, because nothing is voided.
- 2Avoid putting a run line or total at a book that refunds on a pitcher change against one at a book where it stands.
- 3Place MLB hedges as close to first pitch as prices allow, after lineups and starters are confirmed.
- 4Read the pitcher shown on each slip before confirming; a listed moneyline carries the names on the ticket.
- 5If a leg is voided, re-hedge or close the other leg straight away at the new price rather than waiting; hedging covers sizing it.
Finding the prices, keeping the check
The Odds Board compares full-game MLB moneylines, run lines and totals across books so you can see the best price on each side, and the Hedge Finder finds the other side for a bet you already hold. Neither knows whether you chose action or a listed pitcher on the slip, so that check stays with you. The odds board walkthrough shows how to read the rows; house rules covers the other rules worth checking, and overtime and retirement rules the ones for other sports.
Frequently asked questions
- What does action mean in baseball betting?
- Your bet stands whoever starts on the mound, at the odds you took. Most US books default moneylines to action.
- What happens to my bet if the starting pitcher is scratched?
- An action bet stands; a listed-pitcher bet is refunded. Some books also refund totals and run lines on a pitcher change — Circa's Nevada rules do — so check your book's baseball rules.
- Should I bet listed pitchers or action?
- List the pitcher if your reason for the bet is that matchup. For hedges, use the same setting at both books so a scratch cannot void one leg only.
- Do pitcher props get voided if the pitcher doesn't start?
- Usually yes, but the definition varies: FanDuel voids if the listed pitcher doesn't start, Caesars requires him to throw his team's first pitch.
