◆Nippon Life Interleague Series 2026 Seibu Lions 3-0 The Giants (June 12, Belluna Dome)

Seibu Lions won the first game of their final interleague series against The Giants, achieving their third six-game winning streak of the season. Their lead in the standings has also increased to a season-high 17 games. With Softbank Hawks losing to Yakult, Seibu has moved into first place in the interleague series, where they are aiming for their first championship.

Starting pitcher Kosei Takahashi pitched seven scoreless runs, allowing only one hit strike out to earn his seventh win of the season, tying him for the league lead. He gave up a single to cleanup hitter Dalbec with two outs and a hit on first in the first inning, but pitch a no hit thereafter, keeping The Giants lineup from finding a rhythm. This was Takahashi's first win in his fourth appearance against The Giants.

In the first inning, with one out and a runner on first base outfielder Shinya Hasegawa hit a timely doble to left-center field, marking his fifth consecutive game with RBI, giving his team the lead. In the sixth inning, with one out and a runner on third base, infielder Natsuo Takizawa hit a timely single to left field, adding another run. Takizawa then hit a decisive triple down the right field line in the eighth inning.
