San Diego shockingly acquired 100-mph flamethrower Mason Miller from the A’s on Thursday in a massive move ahead of the MLB trade deadline, The Post’s Jon Heyman confirmed. San Diego is also receiving former Yankee lefty JP Sears, while the A’s are receiving four players, including the No. 3 prospect in the sport in shortstop Leo De Vries.

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).
