Overview
- Phil Maton was placed on the 15-day injured list Friday with recurring right knee tendinitis, his second IL stint this season.
- Maton has struggled in 2026 with a 6.08 ERA across 26 2/3 innings after signing a two-year, $14.5 million guaranteed deal in the offseason.
- The Cubs acquired left-hander David Peterson from the New York Mets in exchange for minor-league infielder Cole Mathis and added Peterson to the 26-man roster as an immediate rotation reinforcement.
- Manager Craig Counsell said the club had previously rested Maton and hopes the All-Star break can aid recoveries while Jameson Taillon may make a one-short-start return before the break and Matthew Boyd offers additional, limited relief.
- With roughly a dozen pitchers on the injured list and key starters sidelined, the Cubs face late-inning role juggling and will likely pursue short-term pitching help and controlled rehab timetables ahead of the trade deadline.
