Los Angeles Dodgers relief pitcher Blake Treinen suffered a season-ending shoulder injury during a bullpen warm-up session ahead of Saturday's game against the San Francisco Giants. Manager Dave Roberts confirmed postgame that the thirty-eight-year-old veteran felt a sharp pop in his pitching shoulder, forcing him to immediately halt his pregame routine and exit the field with an athletic trainer. Treinen finishes the regular season with a four and one record and a three point sixty-four earned run average across thirty-six appearances. This development delivers a severe blow to the Dodgers bullpen depth as the team enters its five-day postseason break without a trusted high-leverage relief arm. Roberts must now adjust setup responsibilities by relying on pitchers such as Evan Phillips and potential transition options from the starting rotation to bridge critical innings during the upcoming playoff series.
