Pacific League: Seibu Lions 1-9 Nippon-Ham (26th, Belluna Dome)

Seibu Lions 's starting pitcher, Yutaro Watanabe, pitched six innings, strike out eight, giving up ten hit, and allowing a season-high nine runs (eight earned) before being pulled from the game. He was unable to secure a win at home in his tenth start.

In the first inning, he recorded one out, striking struck out Kiyomiya and Reyes consecutively. In the second inning, he had a runner on first with no outs, but he shut down the subsequent batters.

However, in the third inning, partly due to a teammate's error, he allowed a go-ahead RBI single to center field to Kiyomiya with one out and runners on first and third. In the fourth inning, after his teammates had tied the game, he gave up a three-run RBI triple that split right-center field to Yoshida for a sweep with one out and the bases loaded.

In the fifth inning, he retired the side in order again. However, in the sixth inning—which he called his "biggest point for reflection"—he gave up a two-run homer (his 5th) to Otsuka with no outs and a runner on first, and then a three-run homer (his 15th) to Kiyomiya with two outs and runners on first and third, and was pulled from the game after this inning. "Things really didn't click. There are days like this in a baseball career. Since there's nothing I can do about the past, it's important to produce solid results in the next game," he said, doing his best to stay positive.
