In just under a week, the sounds of leather popping will echo throughout the Carpenter Complex in Clearwater, Fla. Pitchers and catchers will be in full swing (or full throw) as the Phillies prepare for the 2026 World Series campaign.
In an offseason that featured some changes to the position player core and the bullpen, the Phillies’ rotation has remained largely unchanged. Ranger Suárez departing for the Boston Red Sox via free agency and the expected elevation of Andrew Painter are the only changes in sight.
That means the Phillies will rely on five familiar faces alongside the rookie Painter for 2026. From injuries and frustration to breakout seasons, 2025 was a mixed bag for the starting staff. Today, we look at one thing each of the Phillies’ starters needs to prove this Spring Training.
There is very little mystery surrounding Zack Wheeler when he is healthy. The Phillies’ ace has spent the better part of the last half decade establishing himself as one of the most reliable and dominant starting pitchers in baseball. What makes Wheeler’s 2026 outlook unique, however, has nothing to do with ability and everything to do with availability.
Thoracic outlet surgery abruptly cut Wheeler’s 2025 campaign short, creating the first legitimate durability question of his tenure. The right-hander was pitching at his usual elite level before the injury, posting another All-Star caliber season with a 2.71 ERA and continuing his streak as one of baseball’s most valuable starters. When Wheeler takes the mound, he remains the ace of the Phillies’ staff and one of the few pitchers in the sport capable of matching any opposing ace pitch for pitch.
This Spring Training is all about proving Wheeler is healthy and getting him closer to returning. With his rehab projected at six to eight months, Wheeler should return in the first half of the season, but there is a lot of work to be done before reaching that point. As Geoff Mosher described for PhillyVoice, the important thing is that every aspect of Wheeler’s shoulder properly recovers. Wheeler has yet to throw off a mound. Once he does, the goal will be to slowly build him back up to the pitcher that instills fear in hitters across baseball.
Cristopher Sánchez’s breakout 2025 season landed him in second in the National League Cy Young Award voting behind Paul Skenes. Having led the National League in bWAR, Sánchez went from an up-and-coming rotation pitcher to a staff ace.
His success was built on a devastating changeup that overwhelmed hitters all season, paired with dramatically improved command that allowed him to consistently work deep into games. Sánchez’s ability to limit hard contact while maintaining swing-and-miss ability gave the Phillies a stabilizing presence every fifth day. A presence that was much needed during injury-created gaps in the rotation.
Now Sánchez needs to take another step: repeating the same success in 2026. Spring Training will give Sánchez the chance to prove that opposing hitters have yet to crack the code of his performance. If he can keep his command in check, limit walks, and keep batters off-balance, Sánchez may not just be a rotational anchor but the best left-handed starter in baseball in 2026.
Aaron Nola’s career going into 2025 had been defined by durability. Rarely ever missing a start due to injury, the veteran right-hander endured a season of injury and inefficiency. Despite the struggles, Nola did reach new milestones, climbing to second on the franchise’s all-time strikeout record.
The underlying question entering 2026 is whether last season was a temporary disruption or the beginning of regression. Historically, Nola’s success has been tied to elite command. Namely, his ability to control the strike zone early in counts while limiting damaging contact. When that precision slips, his margin for error narrows considerably, often resulting in his trademark one home run per game.
Aaron Nola is coming off the worst season of his career. There is no sugar-coating that fact. This Spring Training will be the first indication as to whether that bad season will become a blip on his career or a new trend as he treks further into the second half of his career and into year three of his seven-year, $172 million contract. The signs are simple: Is the command there, and can he stay in control on the mound?
Jesús Luzardo’s first season in Philadelphia delivered exactly what the Phillies envisioned when they acquired him: high strikeout upside paired with top-of-the-rotation durability. The left-hander reached new career highs in innings, strikeouts, and wins, providing a dynamic complement to Cristopher Sánchez on the left side of the rotation.
Luzardo’s season was defined by dominance in stretches, including an extended early-season run in which he consistently limited opposing offenses. His swing-and-miss arsenal allows him to overpower lineups, but occasional inconsistency in run prevention kept his ERA higher than his underlying metrics suggested.
In 2026, the goal for Luzardo focuses on refinement rather than reinvention. In Spring Training, consistency and better pitch sequencing should be the primary targets. If he can continue his strikeout dominance with a more pitch-efficient approach, Luzardo will have all the tools he needs to complement Sánchez as the best left-handed duo in all of baseball.
Few players carry long-term intrigue quite like Andrew Painter. Lauded as a future ace of the Phillies’ staff, Painter’s Tommy John surgery delayed his ascent by a couple of years. Now, Painter stands waiting on the doorstep.
Painter’s velocity, pitch mix, and poise beyond his years have stayed constant through his recovery. Now, he needs to demonstrate the consistent command and physical durability required to turn over major league lineups several times per start.
While Painter is presumed to make the starting rotation to begin the season, Spring Training will act as his final audition for the role. After all this time, is the 22-year-old the Phillies drafted out of high school ready for The Show? A pitcher does not need to dominate in Grapefruit League action but rather demonstrate strong, repeatable mechanics and composure against veteran bats. If he does, he will be positioned to play a critical role in the Phillies’ 2026 campaign.
In the final year of his four-year, $72 million contract with the Phillies, Taijuan Walker will continue to play his secondary swing role between the starting rotation and the bullpen. Rebounding well in 2025 after an abysmal 2024 season, Walker contributed valuable innings in both starting and relief roles.
Walker’s success last season stemmed largely from improved ground-ball tendencies and more efficient pitch selection early on in counts. When he was efficient, he proved capable of navigating lineups effectively. However, prolonged outings against opposing batting orders began to wear him down.
Entering Spring Training, Walker lines up to retain his swingman role, with an early chance in the rotation as Wheeler continues his recovery. If Walker wants to stay in the rotation past that, his chances start in Spring Training as he needs to demonstrate that he can be looked to to consistently turn lineups over in-game. Regardless, his versatility and veteran experience will have value entering what is a contract year for the 33-year-old.
While teams across Major League Baseball have made noise this offseason with their acquisitions, the Phillies’ rotation has been a quiet front, and for good reason. While there are several question marks, the Phillies have the potential to own, yet again, one of the strongest starting rotations in baseball in 2026.
If the Phillies want that hope to become a reality, however, the onus is on the pitchers themselves to make it happen. Aaron Nola needs to return to form, Zack Wheeler needs to return healthy and capable, and Andrew Painter needs to prove that he is ready to contribute at the major league level.
