The World Baseball Classic may involve 16 nations, but this year's tournament has looked more like a Japan-South Korea invitational.

The two Asian nations have faced each other four times in the WBC and will meet for a fifth time in the final if Japan defeats the United States in its semifinal game on Sunday.

There's a saying that familiarity breeds contempt, and it's likely many fans are growing weary of Japan facing South Korea at the WBC.
