Japan’s Nippon Professional Baseball postseason opened with twin upsets as both Pacific and Central League runner-up teams were eliminated in the first stage. With KBO League playoffs starting October 14, 2026, featuring a Jamsil Derby wild-card series between the LG Twins and Doosan Bears, teams face heightened pressure to avoid a similar fate.
First-Stage Upsets Sweep Japanese Professional Baseball
The opening stage of the Nippon Professional Baseball postseason delivered a severe blow to higher-seeded clubs playing on home soil. Central League runner-up Yomiuri Giants and Pacific League runner-up Saitama Seibu Lions both exited the playoffs early, stuns that rippled across baseball communities in East Asia.
Yomiuri hosted the Yokohama DeNA BayStars at the Tokyo Dome but dropped two consecutive games to lose the series 0-2. Meanwhile, Seibu welcomed the Hokkaido Nippon-Ham Fighters to Belluna Dome, where the visitors capitalized on late-season momentum to eliminate the hosts. Both third-place challengers advanced, proving that regular-season standings and home-field advantages offer little safety in short playoff series.
Jamsil Stadium Sets the Stage for KBO Wild-Card Drama
As the Nippon Professional Baseball results drew attention across the region, the KBO League finalized its 2026 regular-season standings following final games on October 12. The opening round of the KBO postseason delivers an immediate cross-town rivalry known as the Jamsil Derby.
The fourth-place LG Twins and fifth-place Doosan Bears will square off at Seoul’s Jamsil Stadium beginning October 14. Under KBO wild-card rules, the higher-seeded LG squad enters the series holding a one-win advantage. LG requires just a single win or a tie across the series to advance to the semi-playoffs and face the Kia Tigers, while Doosan must secure consecutive victories to overturn the deficit.
Historical Precedents and Roster Pressures Shape the Matchup
Systemic advantages heavily favor the LG Twins on paper, but short-series volatility remains a constant threat. In the 2024 KBO wild-card series, the fifth-place KT Wiz broke historical precedent by defeating the fourth-place Doosan Bears to secure the first-ever upset by a lower seed in the round.
For the LG Twins, the sudden exits of Yomiuri and Seibu in Japan serve as an uncomfortable warning regarding the dangers of lost momentum. For the Doosan Bears, entering as the underdog provides clear motivation as they attempt to replicate those regional upsets on home turf.
