On Day 11 of the 107th Kanagawa Prefectural High School Baseball Championship, eight quarterfinal matches were held across four stadiums, including Yokohama Stadium, determining the tournament’s top eight teams.

Koryo Gakuen, whose manager Masayuki Noro (64) announced his retirement after this summer, faced off against Nihon University Fujisawa but lost 4-6 in a high-scoring game. Top-seeded Soyang fell behind early, conceding three runs by the fourth inning due to a home run by Kochiya Kohei (3rd year) of Kojyo, and despite scoring two runs in the sixth, they couldn’t recover.

Tokai University Sagami’s batting lineup exploded, leading to an 8th-inning mercy rule victory over Hosei Second. Yokohama’s right-handed pitcher Shoki Oda (2nd year) held Fujisawa’s lineup to just one irregular-bounce hit, securing a shutout win. Nihon University, led by ace left-handed pitcher Shungo Kawamura (3rd year), defeated Seisa Kokusai Shonan, advancing to the quarterfinals for the first time in eight years. Hiratsuka Gakuen returned after a decade (excluding replacement tournaments).

Among the top eight teams, three—Hiratsuka Gakuen, Fujisawa Shoryo, and Nihon University Fujisawa—were unseeded.

No games are scheduled for the 21st, with the quarterfinals set to take place on the 22nd across four prefectural stadiums.
