The Athletics lost one of the best relievers in baseball, but acquiring the No. 3 overall prospect for a reliever is a home run.

At the trade deadline, the A's parted ways with their star closer and fan favorite Mason Miller, leaving a big hole in the ninth inning.

The San Diego Padres have landed closer Mason Miller and left-handed starting pitcher JP Sears from the Athletics in a blockbuster trade deadline deal, the team announced Thursday. The return includes top shortstop prospect Leodalis De Vries, who ranked No. 3 on CBS Sports' midseason rankings.
