The United States doubled their World Baseball Classic run tally in two innings against Canada on Monday night.
Mike Trout and Trea Turner hit home runs to put the Americans up by double digits by the end of the second inning.
The Americans needed a strong response inside Chase Field after they lost 11-5 to Mexico in Pool C on Sunday.
Not only did Team USA get back on track, it also saved some pitching for the final two Pool C games since it won by way of the run over Canada.
The run rule was used two other times on Monday.
