MLB RBI props: will he drive in a run?

• A home run is at least one RBI.
• Runs scored on errors usually do not count.
• Hitters in the middle of the order get more chances.
• The batter must start for action at most books.

The official scorer decides each RBI.

A hit that scores a runner is an RBI. So is a sacrifice fly, a ground out that scores a runner from third, and a walk or hit by pitch with the bases loaded.

A home run counts the batter himself plus any runners on base. A grand slam is four RBIs.

No RBI is given when a run scores on an error, or when the batter grounds into a double play. The scorer can also deny an RBI on some fielders choice plays.

Runners on base create RBI chances. Hitters behind high on-base players see far more men on base than those behind weak hitters.

The opposing pitcher and park matter. A hitter-friendly park and a weak starter raise the chance of runs for the whole lineup.

The game total is a good guide. A game with a total of 10 suggests more runs, and more runs mean more RBIs to go around.

   Odds vary.

Most books need the batter to start for action. Some need only one plate appearance, so read the rule for late lineup changes.

If a game is shortened by rain, many books need it to be official, usually 5 innings, for props to stand.

Official scoring can change the next day. Books usually settle on the stats at the end of the game.

A cleanup hitter has an RBI line of 0.5 at +125 over. The game total is 9.5, and the two hitters ahead of him reach base about 36% of the time.

In the first inning he grounds out with a man on third, and the runner scores. That ground out still counts as an RBI, so the over wins.

A $10 bet at +125 returns $22.50. If the run had scored on a throwing error instead, he would get no RBI and would need another chance later in the game. Late in the game, a bases-loaded walk would also count.

Ignoring lineup spot

Fewer runners on base.

Counting errors

No RBI on errors.

Skipping the park

Some parks add runs.

Missing scratches

Check the lineup first.

Some books let you combine RBI props with hits or runs scored for the same batter. These legs move together, so the book prices the parlay below the plain product of the odds.
