Baseball results Monday 21 September 2026: AI predictions review
Baseball results Monday 21 September 2026: AI models went 3 of 3 on NPB games, with Chunichi's 10-0 rout the biggest surprise. Full review and model…
Monday's NPB slate produced a clean sweep for the consensus, with all three pre-match picks landing. The headline record stands at 3 of 3 correct, though the margin of victory in one game was far greater than any model anticipated.
The biggest surprise came in Nagoya, where Chunichi Dragons demolished Hiroshima Carp 10-0. The models had backed Chunichi, but the most common predicted score was a narrow 4-3, and average confidence sat at just 24%. The actual result was a blowout that no single model saw coming.
Where the AI got it right
Chunichi Dragons vs Hiroshima Carp prediction: The consensus picked Chunichi with 60% of models and a most common score of 4-3. The Dragons won 10-0, a far more emphatic result than the models had projected. While the winner was correct, the scoreline was way off.
Hanshin Tigers vs Yokohama BayStars prediction: Hanshin Tigers were the consensus pick with 70% support, though the most common score was a 3-4 defeat. The Tigers actually won 3-2, flipping the predicted margin but delivering the correct winner. Average confidence was 20%.
Nippon Ham Fighters vs Orix Buffaloes prediction: The models backed Nippon Ham with 70% of the vote, most commonly predicting a 4-2 win. The Fighters won 5-3, a two-run margin that matched the predicted gap, though the exact score differed. Average confidence was 18%.
Where it got it wrong
There were no misses on Monday. All three consensus picks — Chunichi, Hanshin and Nippon Ham — proved correct, giving the models a perfect record for the day. The only inaccuracy lay in the scorelines, particularly Chunichi's 10-0 rout, which no model had foreseen.
Models of the day
Three models achieved a perfect 3 of 3: Claude Sonnet 5, Qwen 3.8 Max and Grok 4.6. They correctly identified the winner in every game.
At the other end, GPT-5.6 Luna, Mistral Medium 3.5 and GLM 5.3 each managed only 1 of 3 correct. The remaining four models — DeepSeek V4 Pro, MiMo V2.5 Pro, Gemini 3.8 Flash and Kimi K3 — finished with 2 of 3.
