I hate international extra innings.....I guess for a lot this is the first time they are seeing it but it has been the norm for awhile. Forgetting even the other constraints, a lot of times international tournies are being hosted in single stadiums. To ensure games end on time is part of the reasoning.
Soccer has penalty kicks, hockey has the shootout, and baseball has this.
I actually think I would prefer runner only on 1st, but it starts right away in the 10th. Under that format, I would imagine most games ending by the 12th?
