Roberts (elbow) underwent successful Tommy John surgery Wednesday, Jordan Bastian of MLB.com reports.
Roberts sustained his right elbow injury during a rehab appearance at Triple-A Iowa in late June and will be unavailable for the remainder of the 2022 season and most or all of the 2023 campaign following Wednesday's procedure. The 25-year-old made his major-league debut in 2022 and posted an 8.22 ERA and 2.09 WHIP in 7.2 innings over nine relief appearances.
