Joe Musgrove Makes San Diego Padres Spring Training Debut in 2026

San Diego Padres right-hander Joe Musgrove pitched in a game setting for the first time since his October 2024 Tommy John surgery, taking the mound in a spring training exhibition against Team Great Britain on Wednesday, March 5, 2026. The appearance marked a milestone for a pitcher who spent more than 16 months away from competitive action, arriving at a moment when the club’s starting rotation carries real uncertainty heading into the new campaign.

Musgrove did not simply survive the outing. By his own account, he looked like himself. “I liked the shapes of my stuff,” Musgrove said following the appearance. For a franchise counting on veteran arms at the top of its rotation, that self-assessment carries weight.

What Led to Musgrove’s Tommy John Surgery?

The procedure came in October 2024, ending a prolonged attempt to manage elbow issues during the season. Recovery placed him on a timeline that consumed the entire 2025 campaign, and his March 2026 return represents the first live action he has seen since that operation.

Ulnar collateral ligament reconstruction typically requires 12 to 18 months of rehabilitation before a pitcher returns to game action. Musgrove’s timeline aligns with that standard arc. His absence removed not just innings from the San Diego rotation but the kind of veteran presence that steadies a staff across a 162-game schedule.

The club enters 2026 with questions in the starting rotation, a reality that gives Musgrove’s spring debut added significance beyond the personal milestone. Rotation depth and health represent one of the central storylines of San Diego’s 2026 spring camp, and how Musgrove progresses through the Cactus League schedule will shape how the pitching staff is structured for April and beyond.

His pre-surgery seasons established him as one of the better starters in the National League — a four-year stretch in San Diego defined by weak contact allowed, limited walks, and a strikeout rate that held up against top competition in the NL West. The division, anchored by the Los Angeles Dodgers and San Francisco Giants, demands that level of production from any rotation anchor.

The rotation question extends beyond one pitcher’s health. It is about whether the Padres can field a group capable of competing in a division that annually produces some of the most demanding pitching environments in baseball. Musgrove’s return, if it holds, addresses one concern directly. A full spring slate will determine whether his command and durability match his pre-surgery profile.

What Musgrove Said About His Return

Musgrove framed the debut as a process, not a proclamation. “To me, this is another step,” he said after the outing. That measured tone is consistent with how pitchers returning from major elbow reconstruction typically approach early appearances — managing expectations while building toward a larger goal.

He also addressed his preparation directly. “I’ve been working at a very casual pace for the last couple months,” Musgrove said. Prioritizing tissue health and mechanical consistency over an aggressive ramp-up is standard protocol for post-Tommy John returns, particularly for pitchers carrying significant mileage on their arms.

On the health question — the first and most important variable for any pitcher returning from ligament surgery — Musgrove reported feeling healthy following the outing. Pitchers who flag discomfort in initial appearances often face additional setbacks. A clean bill of health after his first live action is an encouraging early data point.

• Musgrove’s appearance on March 5, 2026 was his first game action since the October 2024 operation — a gap of more than 16 months between competitive outings.
• He stated his goal is to be regaining his previous form as the calendar approaches September and October 2026, framing spring as a long runway rather than a sprint to Opening Day readiness.
• Musgrove explicitly said he does not expect to throw 180 to 200 innings in 2026, signaling that the organization is managing a workload ceiling for the right-hander this season.
• He described his pitch shapes as looking like his pre-surgery profile, citing that as a positive indicator from the outing.

What Musgrove’s Return Means for 2026

Musgrove’s 2026 projection carries a defined ceiling based on his own stated expectations. He said he does not expect to reach 180 to 200 innings this year, which places his likely workload well below a full starter’s load. That is still meaningful production for a rotation in need of reliable arms — but it is not the anchor role he played before the injury.

The more revealing timeline is the one Musgrove outlined himself. His goal is to be regaining his old form as the season moves toward September and October. That framing positions him as a pitcher building toward a postseason peak rather than arriving at full strength on Opening Day. For a club with playoff aspirations, a Musgrove who reaches his pre-surgery level by late summer would be a significant asset in a potential October run.

Tommy John surgery outcomes vary. A single spring appearance against international competition is not a reliable predictor of regular-season performance — the sample is too small, the competition too limited, and the workload too light to draw firm conclusions about where his ERA or strikeout rate will land by July. What Wednesday’s outing confirmed is that the physical process is on schedule and that his mechanics and pitch shapes survived the surgery and rehabilitation intact. That is a necessary condition for a successful return. The coming weeks in the Cactus League will provide more data points and sharpen the picture of what Musgrove can reasonably contribute to the 2026 rotation.
