Matt Waldron Injury Update: Navigating the Recovery Process
San Diego Padres pitcher Matt Waldron is currently working through a recovery timeline following a setback. Known for his rare mastery of the knuckleball, Waldron’s availability is a key point of interest for the Padres’ pitching rotation as he manages a muscle injury and begins his return to professional play.
Understanding the Injury: Mild Oblique Strain
According to reports from ESPN, Waldron suffered a mild oblique strain. In the context of professional pitching, an oblique strain involves a tear or stretch of the muscles located in the abdominal wall. These muscles are critical for the rotational power and stability required during a pitcher’s delivery.
Because of this injury, Waldron has been placed on the 15-day Injured List (IL), a standard MLB designation that allows a player to receive treatment and rehabilitation without occupying a spot on the active 26-man roster.
The Rehabilitation Timeline and Strategy
Recovery from a muscle strain requires a structured approach to ensure the athlete does not re-injure the area upon returning to full-intensity activity. Waldron began a 30-day rehab window on March 27. This window provides a specific timeframe for the player to regain strength and timing.

As part of this process, Waldron may have up to three rehab starts. These starts are typically played in the minor leagues, allowing the coaching and medical staff to monitor his workload and physical response before the Padres make a final decision on his return to the Major League roster.
Player Profile: The Knuckleball Specialist
Matt Waldron is not a conventional pitcher. He utilizes the knuckleball, a high-difficulty pitch designed to move unpredictably. To refine this skill, the Padres arranged for Waldron to consult with legendary knuckleballers Tim Wakefield and R.A. Dickey in 2022, as the organization sought to see the pitch utilized at the highest level again, according to MLB.com.
Waldron’s path to the majors was a steady climb. After playing for the Nebraska Cornhuskers at the University of Nebraska, he was selected in the 18th round of the 2019 MLB Draft by the Cleveland Indians. Since making his MLB debut on June 24, 2023, Waldron has recorded a career win-loss record of 8–15 with a 4.86 ERA and 167 strikeouts through the 2025 season, per Wikipedia.
