Mason Miller made his debut with the San Diego Padres on Friday night, the day after being involved in arguably the biggest trade of the entire deadline. Miller isn't the closer for his new team, however, as was reported on Thursday. So on Friday, he came into the game in the top of the eighth with San Diego holding a 4-1 lead.

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.

To get a picture of why the deal was called an overpay, the entire deal needs to be laid out. The Padres got Miller and Sears from the Athletics, while sending De Vries (3rd overall prospect in baseball), Braden Nett (Padres' 3rd-ranked prospect), Henry Baez (13th-ranked prospect), and Eduarniel Nunez (17th-ranked prospect).
