David Peterson gives Chicago Cubs exactly what they need in team debut, an 8-2 win over Milwaukee Brewers

Left-handed pitcher David Peterson made his Chicago Cubs debut on June 28, 2026, leading the team to an 8-2 victory over the Milwaukee Brewers. Peterson, acquired in a rare June trade, brings a 51.1% ground-ball rate that ranks eighth in MLB, addressing a key weakness for a Cubs pitching staff that has allowed the most home runs in the majors this season. Cubs president of baseball operations Jed Hoyer highlighted Peterson's ability to throw strikes and keep the ball on the ground as critical attributes the team had been lacking.
