The Los Angeles Dodgers acquired pitchers Fayer Ryson and Lotos in a trade

The Dodgers moved Michael Kopech and Blake Treinen to a 60-day injury list, while replenishing the bullpen with personnel changes. On Thursday (May 9 local time), the team claimed right pitcher J.P. Feyerson from the Sidewinders. Feyereisen) and acquired right-hand pitcher Ryan Loutos in a trade from the Cardinals in cash compensation. In order to make room for the 40-man roster of new signings, two right-hand pitchers were transferred to the long-term injury list.

For Kopak, who started this season with an injury to a right shoulder impingement, this roster change is more of a procedural operation. The 29-year-old backup pitcher has been on a standout since joining the Dodgers before last year's trade deadline, averting a 1.13 ERA and making six rescues. The latest news shows that his cowpen training is going well and he is expected to start facing live hitters this weekend. In the case of Evan Phillips, who also started with a 15-day injury list, Copak still has to go through a number of minor league rehab games before he can return, with Phillips originally scheduled to complete seven rehab games, but returned early due to Trenan's injury.

The situation in Trenan is even more dire. The 36-year-old right-handed pitcher has yet to return to pitching practice after being on the 15-day injury list on April 19 with a strained right forearm. MRI showed that the injury was a low-grade strain, and treatment options are limited to recuperation and rehabilitation. The move to the 60-day roster means he won't be activated until mid-June at the earliest, and the team has yet to give a specific timetable for his return. In his first eight appearances of the season, the two-time World Series champion posted a 3.38 ERA and made two rescues.

In terms of new signings, the 32-year-old Fayer Rainson, who played briefly for the Dodgers last year, played two games for the Sidewinders this season, conceding three points on two innings (two self-blame points). The 26-year-old was designated by the Cardinals on Monday to keep a three-game clean sheet after making his major league debut this year, and has also posted a 3.38 NCP in eight triple-A appearances for the Memphis Cardinals.

The changes come as the Dodgers Bullpen faces a tough test, with the team leading the major leagues in 136 innings pitched and set to embark on a 10-game road trip spanning Atlanta, Miami and Phoenix, with 19 games to complete over the next 20 days. The addition of fresh blood will provide more scheduling options for head coach Dave Roberts.
