Saitama vs Tohoku Rakuten Prediction 28 September 2026
📡 Seibu consolidated their grip on second place with a 3-2 win over Rakuten on Sunday, moving one and a half games clear of Nippon-Ham. The visitors remain at the bottom of the standings with a 54-81-1 record, but the opening game at Belluna Dome was decided by just a single run. Monday’s pitching matchup promises to be even more intriguing: Chihiro Sumida goes up against Takayuki Kishi, with both starters boasting ERAs under 3.00.
Seibu have dominated the series, but the last two games have been decided by just a single run.
📊 The overall pattern in the last 10 head-to-head clashes has been tough on Rakuten: Seibu have come out on top nine times, outscoring their rivals 38-20. However, the two most recent meetings have bucked that trend. First, Rakuten edged a 1-0 win, before Seibu responded with a 3-2 victory on Sunday-both games decided by a single run.
Head-to-head statistics Saitama - Tohoku Rakuten

Top-tier pitching keeps the Lions in the race for second place, even without a powerful offense.
The second-best team in the league relies heavily on their pitching staff. By the final week of September, Seibu’s team ERA stood at 2.93-second only to champions Fukuoka-and they had already recorded 18 shutouts. Their offense, meanwhile, operates at a more measured pace, with 486 runs, 105 home runs, and a .366 slugging percentage. That’s why their recent 5-4 and 3-2 victories perfectly fit the club’s profile: Seibu don’t need to run up the score as long as their starters and relievers protect a narrow lead. On Sunday, Hiroshi Kaino closed out another tight win.

Kishi provides Rakuten with a more reliable starting option than their position in the standings might suggest.
Rakuten’s last-place standing and a season tally of just 448 runs explain why they’re rarely tipped as favorites, but recent performances suggest they’re more competitive than the table indicates. This week, they defeated Nippon-Ham 5-3 and 6-0, and kept Sunday’s clash with Seibu within a single run until the very end. Their team ERA of 3.67 trails the hosts, but today much of that gap is offset by Kish, whose individual numbers are significantly stronger than the rest of the rotation.

⚾ Starting Pitchers
Chihiro Sumida, a left-hander, stands out as one of the NPB’s top performers this season: 23 starts, a 10-7 record, 2.22 ERA over 166 innings, allowing 135 hits, striking out 148 batters, and conceding just 49 runs. His WHIP sits at an impressive 0.94. Sumida has also thrown four complete games and three shutouts-leading the league in shutout complete games. He’s more than capable of working six to eight innings on his own, giving opponents very little opportunity to mount any offense.
Takayuki Kishi, a righty, enters with a 4-5 record and a 2.80 ERA. Over 10 starts and 61 innings pitched, he’s allowed 55 hits, struck out 45, and given up 23 runs; his WHIP is 1.15. While he hasn’t recorded any complete games or shutouts this season, just 15 walks across his workload highlight his solid command. At age 41, Kishi no longer eats up innings like he once did, but in his current form he remains one of Rakuten’s most dependable options on the mound.
⭐ Editor’s Prediction
Sumida remains the main argument against siding with this pick, and Rakuten’s nine defeats in their last 10 head-to-head meetings can’t be overlooked. Still, the odds give the visitors a vital cushion, and a closely contested matchup feels like the most natural scenario here. The last two encounters ended 1-0 and 3-2, with Seibu relying primarily on pitching-they’ve scored just 38 more runs than Rakuten over the season. Kishi, with a 2.80 ERA and solid command, is capable of keeping pace with Sumida, meaning Rakuten don’t need to win outright-they just need to keep it close and prevent Seibu from pulling away. In a game where runs are expected to be at a premium, every single run could prove decisive. We’re backing Rakuten with a +1.5 run handicap.
