  Scouting Report & Links      
         
  Scouting Report: Major league veteran reliever with a medium, filled out frame. Low arm slot. Low-90s four-seamer with sink. Solid slider with sweeping action. Also mixes in an occasional cutter and changeup. Induces weak contact, gets swings and misses. Emergency up-and-down bullpen arm. Out of options. Invitation to MLB spring training in 2026.
   Note: The scouting reports of certain veteran minor leaguers acquired via free agency or waivers are abridged and will not be regularly updated or expanded.
