Patrick Sandoval Has Pitched Through a Left‑Foot Blister All Season

Team medical staff are monitoring the blister because it can change a pitcher's push-off and threatens Boston’s rotation stability down the stretch.

Overview

Sandoval allowed seven earned runs over four innings in his most recent start on Sunday, a performance that raised fresh questions about his health and form.
He told reporters that he has been pitching through a blister on his left foot 'basically all season' and received a trainer visit in the fourth inning of that game.
A blister on the push-off foot can reduce stability, alter delivery and hurt command, which helps explain how a seemingly small injury can affect a starter’s results.
The timing matters because the Red Sox have cooled to a 3-7 stretch over 10 games and other rotation pieces, including Jake Bennett, have struggled while top arms like Ranger Suarez, Payton Tolle and Sonny Gray carry more predictability.
For now the club is monitoring Sandoval and treating the issue as a pain‑tolerance matter rather than an immediate injury-list move, making his health a key factor to watch for Boston’s postseason push.
