Prediction: Yokohama DeNA BayStars VS Tokyo Yakult Swallows 2025-07-09
Witty Analysis: The Yakult Swallows vs. DeNA BayStars – A Tale of Two Pitchers
The Tokyo Yakult Swallows, fresh off a 4-0 shutout loss to the DeNA BayStars, are now facing their nemesis again. It’s like asking a recovering alcoholic to host a wine-tasting party—risky, but maybe they’ll surprise us. Meanwhile, the DeNA BayStars, riding a wave of pitching dominance (shoutout to Shota To’s gem), are the bookmakers’ darlings. But let’s not let the odds blind us to the chaos that is NPB.
Key Stats & Context
- DeNA BayStars: 4-0 shutout in their last meeting, with a 3.20 team ERA this season. Their closer, Shota To, has a 1.80 ERA in his last 5 starts.
- Yakult Swallows: 4.50 team ERA, with their starter (Takahashi) surrendering 5 earned runs in a farm league loss. Their offense? A paltry .210 team batting average.
- Injuries/Updates: No major injuries listed, but Yakult’s farm team prospects are struggling—Fukumoto’s 2-run homer in a 4-1 win is their lone bright spot.
Odds Breakdown
- Moneyline: DeNA (-154) vs. Yakult (+238).
- Implied probabilities: DeNA ~61.7%, Yakult ~41.7%.
- Spread: DeNA -1.5 (-177) / Yakult +1.5 (+157).
- Total: 7.5 runs (Under -113 / Over +103).
Data-Driven Bet: DeNA -1.5
Let’s crunch the numbers. The underdog win rate in baseball is 41%, so the favorite (DeNA) should theoretically win 59% of the time. The implied probability from the odds (61.7%) is slightly inflated, but not enough to ignore. Splitting the difference:
- Adjusted EV for DeNA: (59% + 2.75%) = 61.75% → EV ≈ (61.75% * 1.77) - 1 = +6.6%.
The spread (-1.5) is more attractive. DeNA’s pitching staff has held opponents to 2.8 runs per game this season, and the Swallows’ offense is a sieve. Even if Yakult scores a run, DeNA’s 1.5-run cushion feels safe.
Why Not the Under?
The total is 7.5, but DeNA’s shutout performance last time and Yakult’s anemic offense suggest a low-scoring affair. The Under (-113) has a 55.5% implied probability, but with both teams averaging 3.5 runs per game, it’s a coin flip. Stick with the spread.
Final Verdict
Bet: DeNA BayStars -1.5 (-177)
EV: +6.6%
Why: DeNA’s dominant pitching and Yakult’s offensive woes make the spread a smart play. The BayStars are priced as a 61.7% favorite, but their 59% expected win rate (adjusted) still gives them a slight edge. Plus, who doesn’t love a team that shuts you out?
