Take it from Scott Hatteberg, a man who knows exactly what it takes to win 20 in a row.
As soon as Hatteberg's made-for-Hollywood home run off Kansas City reliever Jason Grimsley left the yard at Oakland Coliseum on Sept. 4, 2002, to walk-off the Royals, a banner was unfurled with a simple and round yet patently absurd baseball number: 20.
The "Moneyball" A's, later the subject of a big-time feature film with Brad Pitt as Billy Beane (and Chris Pratt as Hatteberg!) had done something historic, setting the American League record for consecutive victories.
That's almost three weeks of the 162-game grind without a loss.
