The Los Angeles Dodgers moved right-handed reliever Brusdar Graterol to the 15-day injured list Thursday due to right shoulder inflammation while activating catcher Austin Barnes from the 10-day IL.

In corresponding moves, the Dodgers recalled right-hander Ben Casparius from Triple-A Oklahoma City and optioned catcher Hunter Feduccia to Triple-A.

Graterol will miss the beginning of the Dodgers’ postseason run, whether they start in the wild-card round or the National League Divisional Series. Los Angeles has a three-game lead on San Diego in the NL West and a magic number of two to clinch the division, meaning a win Thursday’s series finale with the Padres would do the trick.

Graterol, 26, is one of the Dodgers’ top bullpen arms but has endured an injury-plagued 2024 season.

After missing the first half of the season with a shoulder injury, Graterol finally made his season debut Aug. 6 and threw eight pitches before straining a hamstring and returning to the IL. He returned on Sept. 10 and tossed seven scoreless innings in six appearances in September before his shoulder flared up again.

Graterol has a lifetime 2.78 ERA in 188 games (five starts) for the Minnesota Twins (2019) and Dodgers (2020-24).

Barnes, 34, was placed on the IL on Sept. 16 due to a fractured left big toe. The Dodgers’ No. 2 catcher has appeared in 52 games this season and batted .261 with one homer and 11 RBIs.

Casparius, 25, will begin his third stint with the big-league club after making relief appearances for the Dodgers on Aug. 31 and Sept. 22. He earned the win in his major league debut with one scoreless inning against Arizona and pitched three innings for the Dodgers against Colorado on Sunday before being sent back to the minors.

Feduccia, 27, appeared in his first five MLB games earlier this season, most recently on Saturday. He’s batted 4-for-12 with one RBI.
