On Saturday, May 19th, the Rays started Sergio Romo, and it generated a lot of heated discussion. On Sunday, May 20th, they started him again, and the discussion became a firestorm.
Traditionalists maintained that this was not how the game of baseball should be played. Analytics boosters called this a brilliant step forward to a new era. Brian Kenny is still celebrating somewhere in the MLB Network studios.
In case you somehow missed it, the Rays employed a strategy that some have called an opener, where a good reliever (but not your best) starts the game, and pitches the first inning.
