Moneyball: come le statistiche hanno salvato una squadra di baseball

Davide Bennato113 Comments

Quanti di voi conoscono il termine sabermetrics?
Io l’ho scoperto qualche giorno fa leggendo le mie fonti blog su datamining e dintorni.

La sabermetrics sono le statistiche sul baseball messe a punto dalla Society for American Baseball Research (SABR) da cui il nome.
La società è attiva dalla metà degli ‘anni 70 e lo scopo è quello di elaborare delle misure che aiutino a valutare il valore dei giocatori e il loro contributo alle vittorie della squadra.

Il termine è piuttosto diffuso negli Stati Uniti (le sabermetriche sono stampigliate sul retro delle figurine del baseball) e fra chi si occupa di fantasy sport (la versione USA del Fantacalcio applicati a varie attività sportive) oppure chi ha seguito la serie TV Numbers.

Il termine fra qualche mese sarà piuttosto famoso, o comunque sarà più celebre l’idea che per valutare l’efficienza di una squadra, è necessario avere dati oggettivi o comunque non opinabili come statistiche e analisi quantitative.

Perché?
Perché i cinema avranno presto in programmazione il film Moneyball, con Brad Pitt, Jonah Hill e Philip Seymour Hoffmann.

La storia tratta dal libro Moneyball. The Art of Winning an Unfair Game di Michael Lewis, (qui la voce Wikipedia) racconta la stagione 2002 degli Oakland Athletics, durante la quale per reagire alla partenza di alcune stelle del team assieme a enormi problemi finanziari della squadra, Billy Beane (nel film Brad Pitt) decide di affidarsi alla sabermetrics per elaborare strategie e tattiche per rendere competitivo il team.

Questa la trama in estrema sintesi, così non ci roviniamo il piacere di vedere il film con troppi spoiler. Ovviamente mi aspetto una contrapposizione tra la vecchia scuola – lo sport è cuore e passione – e la nuova scuola – lo sport è datamining e strategia.

Quello che ho scoperto – indagando sul libro – è che il libro stesso è una specie di cult nel mondo del baseball americano.
Pubblicato nel 2003,  oltre ad essere una rapida storia della sabermetrics, sostiene l’idea che una analisi statistica rigorosa possa dare delle importanti indicazioni ai team di baseball.
Il termine è entrato non solo nel gergo del baseball professionale, ma anche nell’immaginario collettivo, come mostra questo fotogramma preso da una puntata dei Simpson.

 

 

 

 

In attesa di vedere il film al cinema – e le discussioni sui settimanali sull’argomento (spero) – una domanda mi ronza in testa, per quanto non sia un appassionato di calcio (e di sport in genere).

Perchè non esiste una FIFAmetrics? O – magari – FIGCmetrics?
Chi legge tecnoetica sa che ho raccontato di interessanti applicazioni del datamining al gioco del calcio, soprattutto nel caso dei mondiali.

Sarebbe interessante valutare in modo statistico e quantitativo le performance delle squadre di serie A. Ipotizzarne un comportamento futuro. Vedere se i giocatori contribuiscono al successo della squadra proporzionalmente al loto valore. Verificare il peso del cattivo arbitraggio su una partita, o rilevare la presenza di bias quando un certo arbitro valuta certe squadre.

A pensarci bene, forse ho capito perché.

    Players are responsible for checking local online gambling laws.
    If you’re after a reliable, exciting and efficient platform, then look
    no further than Fastpay! Fastpay Casino is the absolute jewel in the
    Australian online gambling crown! The support team’s dedication shines
    through in its multilingual capabilities, though English is the
    primary focus for Australia. Email support, while slower,
    offers detailed responses for complex concerns, typically within a few
    hours, and includes a ticketing system for tracking.

    After you have played a few games, you can find personalized recommendations in the
    same main tab, but a little further down. Almost all of these games
    tend to have around 10,000 active users at any given time, so you’ll always find an open game.
    On the Roblox Home page, you can discover which games are trending that day and start
    playing whichever one you fancy. However, what makes it really unique is that it also allows you to create your own games and share
    them online, so the whole community can enjoy your creations.

    Dreams, developed by Media Molecule for PlayStation, gives users
    a user-friendly game-building interface (but only for gaming consoles).
    Within Fortnite Creative Mode, players can create
    their own customized game maps alongside assorted game types and activity challenges that
    exist within the Fortnite universe.

  7. Fair Go Casino’s updated sign-in system includes several time-saving features that players are already praising.
    For those prioritizing speed, push-alerts, and advanced
    device security for their $ balance, the Fair go casino mobile app is the recommended route.
    The app sends out notifications right away when there are
    updates about bonuses, withdrawals of $, or casino promotions.
    For players from Australian, choosing between the mobile app and
    a regular browser has a big impact on how they play at Fair Go Casino.
    Regularly check Fair go casino account history for unfamiliar activity,
    and contact support immediately if discrepancies appear.

    To have a consistent experience, always use secure browsers or the official Fair Go Casino mobile app.

    On mobile, you’re rolling the dice depending on your keyboard,
    saved passwords, and any autofill quirks. If the site feels off or needs captcha every time, it’s probably not the legit entry point.
    Bonus hunters reload multiple times a week, scouring the site for stealth promos hidden behind the paywall.
