Zack Wheeler's overwhelming 97.4% market share stems from his standout 2026 return for the Phillies after thoracic outlet syndrome surgery and blood clot removal that ended his 2025 season. The 36-year-old right-hander posted a 3.00 ERA across 28 starts with a 14-5 record, 193 strikeouts, and velocity comparable to prior ace levels, anchoring a top rotation alongside Cristopher Sánchez and Jesús Luzardo while aiding the team's late push. His recent selection as NL Comeback Player in the MLBPA Players Choice Awards reinforces trader consensus on the official award outcome. Scenarios that could shift probabilities include unexpected voter preference for a different narrative or late statistical adjustments, though Wheeler's documented recovery and production make such outcomes unlikely.
