Is USA out of World Baseball Classic? What loss to Italy means for Americans' chance of advancing to knockout stage

The United States loaded up on talent after narrowly missing out on a World Baseball Classic title in 2023. But it might not even be enough to get them to the quarterfinals.

Team USA was bludgeoned by Italy in Tuesday's pool-play finale, throwing the Americans' hopes into disarray. The night started with a pair of second-inning home runs from Italy, and mistakes allowed the Italian lead to become insurmountable despite a U.S. comeback attempt.

Even with a 3-1 record in pool play, the United States suddenly has reason to be concerned.

Is USA out of World Baseball Classic?

The United States is not out of the World Baseball Classic, but proceed with caution if you want to get your hopes up.

Italy can secure a quarterfinal berth for the USA on Wednesday with a win over Mexico, but a Mexico win could spell serious trouble. 

If Mexico defeats Italy on Wednesday, the chances of the U.S. advancing are highly uncertain and would come down to a fairly complicated runs allowed tiebreaker. While extra innings could make the math complicated, a nine-inning loss for Italy would require the Italians to allow at least five runs for the United States to gain the runs allowed advantage. A low-scoring Italy loss would not be enough for the U.S. to advance.

How can Team USA still advance to quarterfinals?

Americans' rooting interest on Wednesday is clear. If Italy defeats Mexico, both Italy and the United States advance, with the Italians winning Pool B.

If Mexico wins, it would set up a three-way tie with Italy, Mexico and the United States all 3-1 in pool play and each team 1-1 against the other two. In that event, the tiebreaker would determine which two teams advance and which one goes home.

The tiebreaker the race would come down to is runs allowed per defensive outs, but only in games between the tied teams. Games against Great Britain and Brazil would not factor in. Here is where that tiebreaker race stands right now:

Mexico is the de facto home team against Italy, so a loss for the Italians would only include 24 defensive outs unless Mexico wins in walk-off fashion.

If Italy allows four or fewer runs in a nine-inning loss, with 24 defensive outs rather than 27, the team's runs allowed per defensive outs would still be lower than the USA ratio of .204. If Italy allows five or more runs in that scenario and loses, the U.S. would have the advantage, provided Mexico-Italy does not go to extra innings to further complicate the math.

WBC tiebreaker rules

Here are the five procedures to break a tie in the World Baseball Classic standings:

• Record between tied teams
• Runs allowed per defensive outs
• Earned runs allowed per defensive outs
• Highest batting average in games between tied teams
• Determined by draw

A three-way tie between the USA, Italy and Mexico couldn't be determined by record, of course, as each team would be 1-1 against the other two. That would send the tiebreaker to runs allowed per defensive outs.

Two-team ties

Two-team ties in pool play are simple. Because each team plays each team and ties within games aren't possible, the winner of a two-way tie would simply be the winner of the head-to-head game between those two teams. For example, a two-way tie between Mexico and the United States would go to the U.S. 

Three-team ties

Three-team ties are more complicated. With only four games in pool play, head-to-head results are often even. That would be the case in a three-way tie between Mexico, Italy, and the United States, with each team 1-1 against the other two.

If the records between tied teams don’t resolve the tie, the next tiebreaker is runs allowed in games among the tied teams. Because some games can end via mercy rule, the tiebreaker is actually calculated as runs allowed per defensive out rather than total runs allowed, accounting for losses in which a team records only 24 outs and for games that end early due to the mercy rule.

If that still doesn’t resolve the tie, the next tiebreaker is earned runs allowed per defensive out, followed by batting average in games among the tied teams. In the highly unlikely event that none of these criteria determines a winner, a draw would settle the tie.
