Overview

  • Over a six-hour span at the July 31 deadline, Preller executed five trades involving 22 players to address rotation, bullpen and lineup gaps.
  • Preller credited constant check-ins led by assistant GM Josh Stein for building rapport with the Athletics before shifting focus from JP Sears to Mason Miller.
  • To secure Miller and left-hander JP Sears, San Diego parted with top prospect Leo De Vries and a package of other minor league talent.
  • The deadline haul also included depth additions like Ryan O’Hearn, Ramon Laureano, Freddy Fermín, Will Wagner, Nestor Cortes Jr. and Jorge Quintana without increasing payroll.
  • With waiver deadlines approaching and budget pressures after owner Peter Seidler’s passing, analysts suggest signing Eloy Jimenez as a low-commitment power boost.
