The Los Angeles Dodgers place reliever Blake Treinen on the injured list due to inflammation in his right elbow, the team announces ahead of a Saturday game against the Baltimore Orioles. Multiple reports state the move is in response to the elbow issue and that Treinen is unavailable to pitch while he is on the injured list. One report specifies that Treinen is placed on the 15-day injured list. To fill the roster spot, the Dodgers recall right-hander Chayce McDermott from Triple-A Oklahoma City. The recall is scheduled for the middle game of a weekend series at Dodger Stadium against the Orioles. The reports also note that Treinen pitched the previous game, striking out two batters in a scoreless ninth inning on Friday night before the injury-list placement. The Dodgers therefore adjust their bullpen availability and roster composition as the team begins the weekend series against Baltimore.
