The Los Angeles Dodgers have sidelined reliever Blake Treinen, placing the right-hander on the 15-day injured list due to right elbow inflammation. The move was announced before Saturday evening’s game at home against the Baltimore Orioles.
To fill the vacancy on the roster, the Dodgers recalled right-hander Chayce McDermott from their Triple-A affiliate in Oklahoma City.
Treinen, who will turn 38 on June 30, is currently in his sixth year with Los Angeles. Through 29 relief outings this season, he carries a 4-1 record with a 3.52 ERA, 25 strikeouts, 10 walks, and one save. The 2018 All-Star has built an impressive career resume, posting a 49-42 record, 83 saves, and a 2.93 career ERA across 560 appearances — including seven starts — with the Washington Nationals from 2014 to 2017, the Oakland Athletics from 2017 to 2019, and the Dodgers during the 2020-22 and 2024-26 seasons. Over that span, he has recorded 621 strikeouts against 233 walks.
McDermott, 27, is making his second trip to the major leagues this season. His lone prior appearance with the Dodgers came on May 17 against the Angels, when he threw one scoreless inning and struck out a batter. At the big league level, he holds a 0-1 record and an 11.85 ERA over six games, including two starts, having previously seen limited action with the Orioles over the past two seasons.
