[2+2 wannabe]

In both rounds, ties shall be broken in the following order of priority:

1. The winner of head-to-head games between the tied teams;
2. The team allowing the fewest runs per nine innings (RA/9) in head-to-head games between the tied teams;
3. The team allowing the fewest earned runs per nine innings (ERA) in head-to-head games between the tied teams;
4. The team with the highest highest batting average (AVG) in head-to-head games between the tied teams;
5. Drawing of lots, conducted by WBCI.

so if Canada would have lost to Mexico by a close score the US would have not qualified for round 2
