Both teams have already advanced to the second round's San Juan Regional and will play again on March 15. All this game determines is who plays Venezuela in the afternoon of March 12 and who plays the Dominican Republic in the evening.
However, expect an interesting game. Both teams will probably be trying to conserve their pitching, but the game is something of a regional grudge match. Interest in the Cuban team is very high in Puerto Rico and this game should be sold out. Cuba has been accusing Puerto Rico of fomenting protest against the Cuban team. Cuba seems to enjoy its "us against them" attitude.
Cuba's starting pitcher hasn't been determined. Puerto Rico will start Kiko Calero, normally a reliever, on the mound, but the game is likely going to be a parade of pitchers.
