Open Extended ReactionsThe Philadelphia Phillies placed Zack Wheeler on the 15-day IL on Saturday due to a blood clot in his right arm. President of baseball operations Dave Dombrowski said Wheeler was diagnosed with a "right upper extremity blood clot," and few other details were offered. Examples include former New York Mets ace Matt Harvey, who underwent thoracic outlet surgery in 2016 and returned in 2017. In 2013, current Texas Rangers president of baseball operations Chris Young, then a pitcher with the Washington Nationals, underwent thoracic outlet surgery. It should be noted that both Harvey and Young underwent surgery for neurogenic thoracic outlet syndrome (the nerve compression type, which is more common).
