David Peterson, a former MLB All-Star (2025), is not having his best campaign thus far in split time between the Mets and Cubs.
Across 19 total starts and 127 innings pitched, Peterson carries an ERA of 5.39 with 113 strikeouts.
His pWAR is -1.0, and some fans are even calling for him to be cut from the roster, which feels unlikely, but the Cubs may want to consider removing him from a starter role.
In 2025, in his All-Star campaign, Peterson boasted an ERA of 4.22 across 30 total starts.
