SAN DIEGO — South Korean fans shouted "This is Korea" as a part of a cheer during their team's game against Japan at the World Baseball Classic.

For a few moments after the game Tuesday, as the South Korean flag was planted on the mound at PETCO Park to celebrate a 4-1 win, it was hard to argue with them.

South Korea's fans came out in mass and turned the contest into a virtual home game for their team, which improved to 4-2 all-time against Japan in WBC competition.
