Cubs acquire David Peterson from Mets in trade

The Chicago Cubs have acquired left-hander David Peterson from the New York Mets as of June 25, 2026. The Cubs are sending corner infielder Cole Mathis to the Mets in this trade. This move comes in response to significant injuries within the Cubs' starting rotation, including the loss of Cade Horton for the season and extended absences of Jameson Taillon and Edward Cabrera. Peterson has struggled recently, holding a 6.09 ERA this season, but the Cubs see potential in his ability to improve in a new environment. The Cubs aim to fortify their pitching depth moving forward.
