After recasting himself as a reliever this season because recurring shoulder weakness prohibited his ability to pitch deep into games as a starter, Carlos Martinez had a “small” surgical procedure late last week to encourage healing in the joint this winter.
Martinez received an injection of platelet-rich plasma (PRP) into the right shoulder, president of baseball operations John Mozeliak confirmed to The Post-Dispatch on Sunday after first disclosing the treatment on KMOX (1120 AM) during his weekly appearance. Mozeliak called it a “small procedure,” and the Cardinals do not expect recovery to intrude on his offseason or delay his availability for spring training.
