Kitayama has delivered 13 quality starts, tossed three complete games, and recorded two shutouts. Opposing hitters manage only a .202 average against him, and his strong win-loss record underscores his consistency throughout the campaign.
Haruya Tanaka, also a righty, owns a 4.13 ERA across 14 starts with a 2-5 mark. Over 76.1 innings, he's surrendered 73 hits, fanned 68, and allowed 39 runs for a 1.31 WHIP.

⭐ Editor’s Prediction
The key advantage for Nippon-Ham is on the mound: Kitayama boasts a 2.39 ERA and a 0.96 WHIP, compared to Tanaka’s 4.13 ERA and 1.31 WHIP, along with nearly three times as many wins. Lotte are coming off a rough stretch, conceding 23 runs over their last three games against Fukuoka, while the hosts wrapped up their previous series with a convincing 7-1 win over Seibu. Nippon-Ham lead the recent head-to-head 6-4 over the last ten meetings, and hold a 13-8 edge across the season. Reyes and company will face a more favorable opposing starter, and if the hosts get ahead early, Yanagawa and the bullpen should be able to protect the lead. The pick here is a Nippon-Ham win.
