Tohoku Rakuten Golden Eagles by 1
Hmm, well isn't this quite the predicament. You have the Hanshin Tigers with a superior regular season record, but recent performances look weaker than a kitten's mew. Seems like they're stuck in a rut, and you know what they say about ruts: the only difference between a rut and a grave are the dimensions.
On the other hand, you have the Tohoku Rakuten Golden Eagles. Their season record might not be the stuff of legend, but they've got something going for them - they are in a rarified state of 'winning against the Tigers' flow. Last encounters are pointing in their favor, looks like they've figured something out.
This matchup reminds me of a mongoose up against a cobra. The cobra might be the favorite but ask yourself, who has the winning record in that battle? It's the pesky mongoose. Sometimes it doesn't matter how fearsome you are if your opponent knows how to quickly slide in and land a punch on the nose...sorry, I mean a bite.
Considering everything, I'd wager that Rakuten's got a decent shot of pulling a sneaky win against the Tigers here - in spite of what the general consensus might be.
