KBO Hits 11 Million Fans in Record-Breaking Pace
On September 12, the KBO League officially surpassed 11 million total attendance for the 2026 season, reaching 11,049,504 fans across just 626 games. This milestone was achieved 17 games faster than last year's record pace and marks the first time the league has crossed the 11 million mark in its history. The achievement underscores the league's status as the most popular sports league in South Korea, with average per-game attendance remaining robust despite the late-season schedule.

Veteran MLB Pitcher Mike Clevinger Joins KBO Roster
Former Cleveland Guardians and Chicago White Sox starter Mike Clevinger has signed a contract with a KBO team after being released by the Pittsburgh Pirates. Clevinger, who posted a 3.55 ERA over nine MLB seasons, represents the latest high-profile American import joining the league for the postseason push. His addition highlights the KBO’s continued ability to attract experienced Major League talent as teams strengthen their rotations for the playoffs.

Kim Ha-seong Maintains Elite Plate Discipline in MLB
Atlanta Braves infielder Kim Ha-seong continues to demonstrate high-level performance in MLB, extending his on-base streak to three consecutive games as of September 13. Despite unlucky batted balls finding fielders, Ha-seong’s expected batting average (xBA) remains near .440, reflecting his elite contact skills and plate discipline. His success serves as a benchmark for current KBO players eyeing future posting opportunities to the Major Leagues.

Local view
Local media outlets are heavily focusing on the "baseball fever" phenomenon driving record crowds. Sports Chosun highlighted that the 11 million milestone was reached in the fewest games ever, attributing the surge to improved fan experience and competitive parity among teams. Money Today noted that the attendance surge is not limited to traditional powerhouses; even mid-tier teams are seeing significant increases in average per-game figures, suggesting a broad-based revival of interest in professional baseball across the country.
