The Cubs placed Ben Brown and Edward Cabrera on the 15-day injured list on Wednesday, adding to their injury woes in their rotation. Brown has a neck strain, and Cabrera is sidelined with a left hamstring strain.
Jameson Taillon, Cade Horton and Justin Steele are also on the IL. Matthew Boyd is set to come off the injured list and start in Brown’s spot in Thursday’s series finale against the Mets.
New York received minor-league slugger and infielder Cole Mathis in the trade. The 22-year-old Mathis, a second-round pick in the 2024 amateur draft, is batting .272 with 10 homers and 39 RBIs in 39 games over two stops this year.
The 30-year-old Peterson is 3-6 with a 6.09 ERA in eight starts and eight relief appearances this year. He is eligible for free agency after this season.
