San Diego, CA – The San Diego Padres are bracing for the likelihood that ace right-hander Joe Musgrove will begin the 2025 Major League Baseball season on the injured list. Musgrove, who missed the entirety of the 2024 season following Tommy John surgery, has experienced a slow and deliberate recovery process, casting doubt on his availability for Opening Day on March 26 against the Detroit Tigers at Petco Park.
Musgrove’s most recent on-field activity came during a spring training exhibition game on March 4, where he made his first appearance since his surgery. Facing a talented Great Britain squad in Peoria, Arizona, as part of the lead-up to the World Baseball Classic, Musgrove pitched two-plus innings. During his outing, he registered three strikeouts and surrendered one run on five singles. Notably, his fastball was clocked at a respectable 95 mph, a promising sign for a pitcher on the comeback trail.
However, the progress has been gradual, and Musgrove has not thrown a baseball in a competitive setting since that March 4 appearance. Padres manager Craig Stammen confirmed the team’s concerns to reporters on Monday, stating that Musgrove is indeed expected to open the season on the IL. This development presents a significant hurdle for a Padres team aiming to contend in a highly competitive National League West division.
A Challenging Road Back from Tommy John Surgery
Tommy John surgery, a reconstructive procedure for the ulnar collateral ligament (UCL) in the elbow, is a common but serious injury for pitchers. The recovery timeline is typically extensive, often requiring 12 to 18 months before a pitcher can return to full competitive form. Musgrove’s situation is particularly poignant given his last full season in 2024, where he was a key contributor for the Padres before his season was cut short by injury.
In his 19 regular-season starts in 2024, Musgrove posted a respectable 6-5 record with a 3.88 earned run average. His promising season came to an abrupt end on October 2, when he was removed early from a critical Wild Card round game against the Atlanta Braves. The diagnosis, delivered just two days later, confirmed a torn UCL, necessitating the surgery that has kept him sidelined ever since.
Musgrove himself acknowledged the long-term nature of recovery from such a procedure in his post-outing comments on March 4. "I’ve talked to a lot of guys that say they don’t feel normal or don’t feel back to themselves (until) about that two-year mark," he stated. "I’ve got all these things that I’m aware of, but I’m not really trying to put myself into one of those classes right now. I’m kind of just taking the ball every fifth day and see how I recover and adjust as we go." This measured approach underscores the mental and physical fortitude required to navigate a comeback from a major surgery.
Career Overview and Impact on the Padres’ Rotation
Joe Musgrove has established himself as a reliable and impactful pitcher throughout his nine-year MLB career. Before joining the Padres, he spent time with the Houston Astros (2016-17) and the Pittsburgh Pirates (2018-20). Across his tenure with these three organizations, Musgrove has compiled a career record of 66-62 with a 3.73 ERA in 206 appearances, 180 of which were starts. His ability to consistently perform at a high level made him a cornerstone of the Padres’ pitching staff.
His absence to start the 2025 season will undoubtedly create a void in the Padres’ starting rotation. The team had been hopeful that Musgrove would be ready to anchor the staff, providing crucial innings and leadership. His initial spring training outing offered a glimmer of hope, but the subsequent lack of throwing has tempered those expectations.
The Padres’ starting rotation will need to absorb the loss of Musgrove’s presence. The team will likely rely on a combination of returning pitchers and potential acquisitions to fill the gap. Key figures in the rotation will need to step up to ensure the team remains competitive from the outset of the season. This scenario places increased pressure on pitchers like Yu Darvish, Blake Snell (if re-signed or if the team makes a move to acquire another ace), and the younger arms in the organization.

Supporting Data: Tommy John Surgery and Pitcher Performance
The impact of Tommy John surgery on pitchers is well-documented in baseball analytics. While many pitchers successfully return and achieve a high level of performance, the road is often fraught with challenges. Studies have shown that while velocity can often be regained, command and consistency can take longer to re-establish. The psychological aspect of returning to the mound after such a significant injury also plays a crucial role in a pitcher’s comeback.
For Musgrove, the 95 mph fastball velocity in his March 4 outing is a positive indicator, suggesting that the physical rebuilding of his arm is progressing well. However, the ability to sustain that velocity and command it effectively over a full outing, and then over a season, is the true test. The fact that he has not thrown since that appearance suggests that the team and medical staff are prioritizing a meticulous and cautious approach to his return, aiming to avoid any setbacks.
The "two-year mark" Musgrove referenced is often cited by pitchers as the point when they feel fully "themselves" again. This highlights that even beyond the physical healing, there’s a period of adaptation and reintegration into the rigors of professional baseball. For Musgrove, who is aiming for a full recovery and sustained performance, this timeline suggests a patient approach is indeed warranted.
Broader Implications for the Padres’ Season Outlook
The potential absence of Joe Musgrove for Opening Day has significant implications for the San Diego Padres’ aspirations in the 2025 season. The team has made considerable investments in its roster with the stated goal of competing for a World Series title. A strong starting rotation is a fundamental prerequisite for such a pursuit.
The Padres’ front office will be closely monitoring Musgrove’s progress and will undoubtedly have contingency plans in place. This could involve an increased reliance on their minor league system to develop potential replacements or exploring free agent and trade markets for pitching reinforcements. The team’s ability to navigate Musgrove’s absence effectively will be a key determinant of their early-season success and their overall trajectory for the year.
Furthermore, the situation underscores the inherent risks and unpredictability associated with pitcher injuries. Even the most elite pitchers are vulnerable to setbacks, and teams must be prepared to adapt to unforeseen circumstances. The Padres’ depth and resilience will be tested in the early weeks of the season as they seek to compensate for the loss of their ace.
Official Responses and Team Strategy
While manager Craig Stammen’s comments provided a clear indication of the team’s current assessment, further statements from the Padres’ front office or medical staff might offer more specific details on Musgrove’s rehabilitation program and projected return timeline. However, in the professional sports world, teams often maintain a degree of discretion regarding player injuries and recovery plans.
The team’s strategy will likely involve a phased return for Musgrove once he is cleared to pitch. This would typically begin with simulated games or short outings in the minor leagues before he is deemed ready for a full MLB start. The goal will be to ensure he is not only healthy but also fully prepared to contribute at his highest level, minimizing the risk of re-injury.
The Padres’ decision to place Musgrove on the IL at the start of the season, while disappointing, is a pragmatic move designed to protect the player and the long-term interests of the franchise. Prioritizing his complete recovery over a potentially rushed return for Opening Day is a common and often wise strategy for teams with championship aspirations. The coming weeks will reveal more about the specifics of his rehabilitation and the team’s adjustments to their pitching staff.
