When placing an arb on baseball, there are a few things you must check before placing the arb.

1. Make sure the bet is either “action” or “listed”

By placing a bet on the “action”, you are tied into the line no matter what — even if there are any late pitching changes.
If you choose to bet the “listed” pitcher, your bet will only be valid if the pitchers listed at the time you placed your wager take the mound.

2. Check that the starting pitchers are the same on both bookmakers

Bookmaker might have different starting pitchers listed on the same baseball match. If the listed starting pitchers do not start, the bet will be void. That is why you must check that the listed starting pitchers are the same on both bookmakers.

3. Check that the time of the match is the same on both bookmakers

Sometimes, the same two baseball teams can meet each other twice on the same day. And because bookmakers use different time zones and daylight savings, our servers might match two different games (on the same day) together. That is why you must double check that you are placing your bets on the same match.
