The San Diego Padres pulled off a big trade when they acquired Mason Miller from the Athletics, but Mike Shildt didn't guarantee anything.

Preller brought flame-throwing closer Mason Miller along with starter J.P. Sears to San Diego in a deal with the A’s, trading away No. 3 overall prospect Leo De Vries and three other top-20 prospects in the Padres’ system.

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).
