Phillies Place Zack Wheeler On Injured List With Blood Clot

By Anthony Franco | August 16, 2025 at 5:55pm CDT

The Phillies announced that Zack Wheeler has been placed on the 15-day injured list due to a right upper extremity blood clot. According to Charlotte Varnes of The Athletic, the clot is near his throwing shoulder. The team has not announced a timetable for his return.

Philadelphia will activate Aaron Nola from the 60-day IL tomorrow. He’s listed as the probable starter for their series finale in Washington. They initially intended to go with a six-man rotation. Instead, Nola will take Wheeler’s spot in a five-man staff that also includes Cristopher Sánchez, Ranger Suárez, Jesús Luzardo and Taijuan Walker. They’ll still need to open a 40-man roster spot for Nola and make an active roster transaction to clear space for Alec Bohm, who is expected back from a 10-day IL stint tomorrow.

The immediate roster considerations take a back seat to concern about Wheeler’s future. The Phils should be able to withstand a short-term absence, at least with regard to the division. They’ve built a five-game lead over the Mets in the NL East. Their hold on the #2 seed in the National League and the associated first-round bye is tenuous. They’re only half a game up on the Dodgers and Padres, who enter play Saturday night tied for the NL West lead. (San Diego and L.A. are playing one another, so one of them will tie Philly this evening.) The scorching hot Brewers have pulled well ahead of the pack for the NL’s top seed.

If this requires a longer-term absence, it’d obviously be a massive blow. Wheeler remains on the short list for the title of MLB’s best pitcher. He has a 2.71 earned run average and leads the majors with 195 strikeouts. He’s averaging more than six innings per start. This will probably be Wheeler’s second consecutive sub-3.00 ERA showing and his fifth time allowing fewer than three earned runs per nine over his six seasons in Philadelphia. Wheeler has been exceptionally durable. This is just his second IL stint as a Phillie, with the other being a month-long absence due to forearm tendinitis in 2022.

A healthy Wheeler would be Philadelphia’s Game 1 starter. There’s no indication that the team is concerned about his playoff availability, but a blood clot comes with a level of uncertainty. The Phillies will presumably provide more specifics in the next few days.

        They ran a MRI 10 days ago. He’s obviously looked off for probably close to a month now. Yet they continued to insist that nothing was wrong. Why skip a start? Why throw him on the IL out of precaution. No. They had him take two more starts where he predictably continued to not look like himself. He made two starts after a MRI with a blood clot in his shoulder. I’m sorry, that’s malpractice. And obviously it was on a lower key, but they did a similar song and dance in saying Harper wasn’t injured earlier on in the year, and then suddenly he’s out for a month.

          Really bad take. Wheeler was still throwing 96-97 with movement, just couldn’t locate, both before and after coming off 10 days rest. MRI shows nothing. Seems to me you are dismissed.

    Even as a Braves fan I feel for this guy who seems to have the Cy elude him every year. At least it’s not because of a Gagne-like result (elite closer with help), but still. Only getting older and he’s been the most consistent pitcher of this decade. Hope he can get back on the horse and finish as a finalist a few more times…while somehow taking a L in every game he’s opposing ATL.

    This is real serious, I know he discuss retiring after this contract ends, I wonder now if he will reconsider and may walk away earlier now. Family comes before baseball. He’ll more than likely be on blood thinners after surgery, then there is rehabbing the shoulder, this is worse than a TJ recovery. Hoping for a solid health recovery for Zack Wheeler. Prayers to him and his family.

    This is no small matter about Wheeler. This could involve surgery to physically remove the clot and/or dissolving the clot by injecting medication through a catheter, plus anticoagulation. He could be out a while, and if he’s on anticoagulants, he’ll have to exert a whole different level of caution when he pitches.

    Duran bears more watching before everyone starts forgetting about yesterday’s line drive to the right ankle. He has to push off that ankle when he throws, and even if he just sustained a minor bone and/or muscle contusion which will completely heal with time, his velocity and control could be adversely affected for a while. There’s also the possibility of aggravating the injury and converting it into something worse, like a fracture. I get very concerned when I see a pitcher throwing 100+ mph with most pitches, like Duran has. The human arm can only do so much, and more often than not, that kind of stress on the arm can lead to shoulder or elbow damage that requires surgery and prolonged rehab.

    162 games is a long season. A lot is going to change for all the playoff-bound teams before the playoffs begin. Having the two top records in either league may not be a good thing. Teams that drew byes for the first wild card round haven’t done well in recent years.

    All it could take is for an ace to get injured or a slugger to get hit by a pitch in the wrong place for the playoff picture to change on a dime.

    What ever team is healthy and has momentum going into the playoffs usually has a better chance than a team that has cruised there for most of the season..

    What’s the treatment for a blood clot? Pills like blood thinners? Or something more invasive?

      kyle,

      The initial treatment will probably be surgical removal of the clot, and/or insertion of a catheter and infusion of clot-dissolving medications, either followed by aggressive anticoagulation for a prolonged period of time. Considering he’s a professional athlete and otherwise in good health, the treatment plan will undoubtedly be aggressive.

      Wheeler is a class act. I hope and pray, he’ll be able to get past this.

          It just happens from the motion of pitching. The exact thing happened to David Cone back in the day, It’s scary, but luckily they caught it before it traveled anywhere.

    Iirc woody Williams had a similar malady. He should be fine since it was found. Blood thinners, maybe vascular surgery to pick it out. Even drip some tPA on it like they can do now with certain ischemic strokes.

    Likely done for season and post season.
