The Dodgers placed right-hander Blake Treinen on the 15-day injured list with right elbow inflammation ahead of Saturday night's game against the visiting Baltimore Orioles.

Los Angeles recalled right-hander Chayce McDermott from Triple-A Oklahoma City in a corresponding move.

Treinen, who turns 38 on June 30, is in his sixth season with the Dodgers. He has a 4-1 record and 3.52 ERA in 29 relief appearances this season with 25 strikeouts, 10 walks and one save. The 2018 All-Star has a 49-42 record, 83 saves and a career 2.93 ERA over 560 games (seven starts) with the Washington Nationals (2014-17), Oakland Athletics (2017-19) and Dodgers (2020-22; 2024-26). He has tossed 621 strikeouts against 233 walks.

McDermott, 27, is entering his second major league stint of the season. He made one previous appearance with the Dodgers, tossing one shutout inning with a strikeout May 17 against the Angels. He has an 0-1 career record and 11.85 ERA over six games (two starts) at the major league level, pitching sparingly for the Orioles the prior two seasons.
