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.

Mason Miller made his debut with the San Diego Padres on Friday night, plus when he found out that a trade could happen.

Miller was able to speak on the trade and what to expect from him with a new team. Speculation has risen on how the Padres will use him, hinting at a possible change from a closing role to starting games.
