Saitama vs Chiba Lotte Prediction 25 September 2026
📡 Seibu return to the Belluna Dome after back-to-back defeats against Fukuoka-5-6 and 3-10-which trimmed their cushion over Nippon-Ham in the race for second place to just one game. Lotte sit fifth in the standings and are coming off three consecutive losses. The pitching matchup is particularly crucial for this prediction: Kona Takahashi has displayed far more consistency this season compared to Haruya Tanaka.

Head-to-head statistics Saitama - Chiba Lotte

Seibu are under pressure to respond after back-to-back defeats against Fukuoka.
Seibu currently sit second in the standings with a 74-58-4 record, but recent defeats to reigning champions Fukuoka have allowed Nippon-Ham to close the gap. Offensively, Nevin leads the way with 21 home runs, Canario has driven in 50 runs, and Takizawa is hitting .275. The backbone of their success, however, remains pitching: Taira and Sumida rank first and second in the league for ERA, while Kaino has racked up 21 saves. After a disappointing road trip, Seibu now have an ideal opportunity to get back to winning ways against a team with a losing record.
Match Results: Saitama Seibu Lions

Lotte arrive at Belluna Dome on the back of three straight defeats.
Lotte stand at 58-70-3 heading into the series after suffering defeats of 2-4 to Seibu, and 4-6 and 0-1 to Orix. Offensively, Nishikawa has been a bright spot with a .292 average, while Yamaguchi leads the way with 32 home runs and 68 RBIs. Still, recent games have once again highlighted the team’s inconsistency at the plate. While Lotte are capable of explosive performances on any given night, they've now failed to close out three consecutive games.

⚾ Starting Pitchers
Kona Takahashi, a right-hander, enters with a 2.69 ERA across 20 starts this season, posting a 9-6 record. Over 127.1 innings, he has allowed just 95 hits, struck out 104 batters, and surrendered 43 runs, sporting a WHIP of 1.10. Takahashi has delivered 14 quality starts and completed three games. Opponents are hitting only .209 against him, and he’s registered a quality start in 70% of his outings.
Haruya Tanaka, also a righty, owns a 4.17 ERA through 15 starts with a 2-5 record. In 82 innings pitched, Tanaka has given up 81 hits, struck out 76, and allowed 43 runs, with a WHIP of 1.33. He’s produced eight quality starts but allows considerably more baserunners, as opponents are batting .251 against him.
⭐ Editor’s Prediction
The head-to-head record is fairly balanced, so the main argument in favor of the hosts isn’t in the H2H, but rather in the starting pitching matchup and overall pitching quality. Takahashi boasts a 2.69 ERA and a 1.10 WHIP, compared to Tanaka’s 4.17 ERA and 1.33 WHIP, along with a notably better win-loss record. Lotte have dropped three straight completed games, including a 2-4 loss to Seibu themselves, while the hosts, after two tough contests against Fukuoka, now face an opponent much lower in the standings. Nevin and the rest of the middle order should also have more opportunities to generate traffic against Tanaka. If Takahashi delivers his usual six or seven competitive innings, Seibu’s strong pitching staff should allow the hosts to control the late stages. We’re backing a Seibu win.
