Both nations are red hot. Both of them are undefeated. It's Cuba vs. Japan at 5 a.m. ET/7 p.m. Local Time and we have the live stream available, which is brought to you by MLB.com. Cuba and Japan are tied for the top spot in Pool A and today they'll decide the winner of that bracket in the 2013 World Baseball Classic. 

It's only the first round, we know, but Cuba would love to win against Japan. If there's a weakness to Cuba, then it's Japan. Both countries are ranked No. 1 and No. 3 respectively, but though Japan holds the lower ranking, they've dominated international sports, especially the WBC. 

Japan crushed Cuba in the 2006 championship game 10-6 to win the first ever WBC. Then, as Cuba once again entered the tournament as the favorite, Japan eliminated them once again in 2009. Both nations are powerhouses and are packed with stars, but Japan always seems to get the upper hand in their matchups. 

On the mound for Japan today you will find Jenji Otonari. He's a 29-year-old lefty. For the Cubans, 36-year-old Wilber Perez, who's also a lefty, will take the hill for Cuba. 

The game is in Fukuoka, Japan, but ironically, the Cubans will be the home team. This game is an early clash of the titans. Don't miss it!
