Brad Peacock and the Astros were hoping that the right-hander was ready to return to the starting rotation tomorrow, though Peacock will now instead visit with team doctors after feeling soreness in his throwing shoulder, manager A.J. Hinch told reporters (including The Athletic’s Jake Kaplan). Peacock reported the setback a day after a bullpen session on Friday.
Peacock had a 4.13 ERA, 9.4 K/9, and 3.56 K/BB rate over 85 innings for Houston when he first hit the injured list on June 28 due to shoulder inflammation. Aside from a troubling 1.4 HR/9, Peacock has delivered thoroughly solid results at the back of Houston’s rotation this season, holding opponents to just a .295 xwOBA.
The Astros were already known to be looking to add starting pitching at the trade deadline, and today’s news will only intensify that search. Gerrit Cole, Justin Verlander, and Wade Miley provide a lot of strength atop the rotation, though aside from Peacock, the Astros’ other starters have struggled. In the short term, Kaplan notes that Framber Valdez (he of the 5.28 ERA over 46 frames this season) is likely to pitch on Monday or Tuesday as either a starter or as a bulk pitcher behind an opener, with Houston going with a bullpen day for the other game.
