Mercy Rule Loss Ends Era of the Taeguk Mark

South Korea's national baseball team saw its 17-year quest for a World Baseball Classic (WBC) quarterfinal berth end in heartbreak with a 0-10 mercy rule loss to the Dominican Republic in the 2026 tournament. In a game held Friday night (local time) at loanDepot park in Miami, Korea failed to score a single run through seven innings before exiting the tournament.

Starting pitcher Ryu Hyun-jin lasted just 1⅔ innings before imploding, and announced his retirement from international competition after the game. The Taeguk mark worn by one of the greatest pitchers in Korean baseball history came down in this fashion.

Dominican Republic's Overwhelming Firepower

The Dominican Republic deployed an MLB All-Star caliber lineup featuring Vladimir Guerrero Jr., Juan Soto, and Manny Machado to attack Korea's pitching staff from the opening frame. Philadelphia Phillies left-hander Cristofer Sánchez completely shut down the Korean batting order with five scoreless innings and eight strikeouts.

The decisive blow came in the seventh inning. New York Yankees catcher Austin Wells crushed a three-run home run into the upper deck fence, triggering the 10-run mercy rule. Wells, a Dominican-American, couldn't hide his joy: "I feel more Dominican every day."

First Quarterfinal in 17 Years, But...

Korea had generated excitement by reaching the WBC quarterfinals for the first time since the 2009 tournament, a 17-year wait. But the wall presented by the Dominican Republic's juggernaut lineup—considered the tournament's best—proved insurmountable. The Dominicans recorded 51 total runs across five tournament games, the most of any team, showcasing explosive power with an average of more than 10 runs per game.

The Dominican Republic will face the United States, which defeated Canada 5-3, in Sunday's semifinal in Miami. Korean manager Ryu Ji-hyun acknowledged after the game: "The Dominican team proved they are the best in the world."
