The Braves plan to place left-hander Martín Pérez on the 15-day injured list with lower back inflammation, per reporting from MLB Trade Rumors citing The Athletic. The move comes as an unexpected blow to Atlanta's starting rotation just before the postseason begins.
Pérez pitched his last start on Sunday, throwing 79 pitches without apparent difficulty, according to Battery Power. The sudden IL placement suggests the injury may have been developing for some time. The corresponding roster move has not yet been publicly announced.
ESPN reported that Pérez is likely to be sidelined until at least the National League Championship Series. Multiple outlets described the move as leaving Atlanta "short-handed" in its rotation for the postseason, with Yahoo Sports noting the team is now examining its pitching options moving forward.
