CLEARWATER, Fla. – Philadelphia Phillies ace Zack Wheeler took a significant step forward in his recovery from thoracic outlet syndrome on Saturday, throwing his first live batting practice session since August 15th. The session, a crucial milestone in his rehabilitation, signals cautious optimism for the Phillies as they prepare for the 2026 season.
Wheeler underwent surgery in September 2025 to address the condition, which causes compression of the veins in the space between the collarbone and first rib, leading to symptoms like arm swelling, and pain. The recovery process has been closely monitored, and Saturday’s live BP marked a tangible progression.
“It went really well,” Wheeler said after the session, according to reports. “I felt a little bit better in sync. I figured that might happen when you get hitters up there instead of just bullpens. Sometimes you struggle a little bit with timing in the bullpen. I’m happy with today, getting it behind me and accomplishing what I set out to do.”
The 35-year-classic right-hander threw 20 pitches to Rafael Marchan and Garrett Stubbs, utilizing his full repertoire. His fastball velocity reached 93 mph, a promising sign considering the extended layoff and ongoing recovery. While not yet ready for game action, the session provided valuable feedback on his mechanics and overall comfort level.
Wheeler Remains Cautiously Optimistic About Timeline
Wheeler acknowledged that a return to spring training games isn’t imminent, but expressed satisfaction with his progress. He plans to focus on refining his accuracy and gradually increasing velocity in future sessions. “I’m looking forward to the next one, trying to get my pitches a little more precise and build the velocity up a little bit,” he said. “That’s kind of how it usually goes for me in the spring, just trying to build up the fastball each time.”
The exact timeline for Wheeler’s return to the Phillies’ rotation remains uncertain. He stated, “I think I’m probably on schedule,” but refrained from providing a specific date. “I’m taking it one day at a time and hoping for the best. We still have a long way to head, so I’ll just keep focusing and keep pushing.”
Wheeler’s absence was keenly felt by the Phillies in 2025. Since joining the team in 2020, he has established himself as a cornerstone of the rotation, posting a remarkable 2.91 ERA across 157 starts. Before his diagnosis, he was enjoying another strong season, with a 2.71 ERA in 24 starts and earning an All-Star selection.
The Phillies are understandably cautious about rushing Wheeler back, given the complexities of thoracic outlet syndrome. The team will continue to monitor his progress closely, prioritizing his long-term health and ensuring he’s fully prepared before returning to competitive action. Thoracic outlet syndrome can present differently in each patient, and a careful, individualized approach to rehabilitation is crucial.
Beyond Wheeler, the Phillies received positive updates on other injured players. Right-handed pitcher Orion Kerkering, recovering from a mild Grade 1 hamstring strain, likewise threw a live batting practice session on Saturday. Manager Rob Thomson indicated Kerkering “possibly” may have enough time to ramp up and be ready for Opening Day, according to Phillies Nation.
Infielder Aidan Miller, however, faces a more uncertain outlook. He has yet to build his Grapefruit League debut due to low back soreness and has not swung a bat in two weeks. Thomson suggested Miller could potentially miss the opening game of the minor league season.
The Phillies’ medical staff will continue to evaluate all three players, adjusting their rehabilitation programs as needed. The team’s success in 2026 will undoubtedly hinge, in part, on the timely returns of these key contributors.
Wheeler’s progress is particularly encouraging, offering a glimmer of hope for a Phillies team aiming to contend in a competitive National League East. His ability to regain his form will be critical as the team navigates a challenging schedule and strives for postseason success.
The next step for Wheeler will be a two-inning live BP session in the coming days, if Saturday’s session is deemed successful. He will almost certainly begin the season on the 15-day injured list, but the Phillies are optimistic he won’t be sidelined for an extended period.
As Wheeler continues his journey back to the mound, Phillies fans will be watching with anticipation, hoping to see their ace return to his dominant form and lead the team back to the playoffs.
