The Padres made 22 player moves ahead of Thursday’s trade deadline, acquiring key pieces to bolster their bullpen and offense for a playoff run.

In a startling move that sends the game’s most dominant reliever across the state and to another league, the Athletics have agreed to trade Mason Miller to the San Diego Padres, perhaps signaling a greater revamp to come at Petco Park, according to a person with knowledge of the deal.

The Athletics reportedly traded star closer Mason Miller and starting pitcher J.P. Sears to the Padres for four players, including a top prospect.
