The only two times since 1991 that the NASOMA World Series went 7 games were 2003 and 2015. And yes, the Warpigs won both - but there were some other similarities that bear mentioning...
In both series, the Warpigs were down 3 games to 1, and in both series they came back to win 3 straight.
Both series had a Game 6 come-from-behind last inning. In both years, the Pigs trailed 2-1 going into their last at bat of game 6. In 2003, the Pigs scored 2 in the top of the 9th to beat the Drillers 3-2. In 2015, the Pigs scored 3 in the bottom of the 12th to beat the Sidewinders 4-2.
In game 6 in 2003, the 9th inning winning runs scored on back-to-back-to-back doubles. In game 7 in 2015, the winning runs scored on back-to-back-to-back doubles.
But here's the weirdest thing... In game 7 in 2003, the key moment was Barry Bonds batting against David Williams with the tying run at 1st and 1 out. The ONLY chance for a double play - other than an x-chance, was a roll of 6-2. And that's what he rolled. In game 6 in 2015, the key moment was Beltre's at bat in the bottom of the 12th. The roll was 6-2 for a ballpark homer. Both key moments came on rolls of 6-2. Weird stuff.
