Hess announced Wednesday via his personal Twitter account that he will begin chemotherapy next week after he was recently diagnosed with a cancerous germ cell tumor in the center of his chest.
The 28-year-old right-hander expressed confidence that through treatment, the cancerous tumor will hopefully be eradicated and allow him to resume his baseball career. Hess spent time in the Marlins and Rays organizations in 2021, appearing in 15 games at the MLB level and posting a 9.90 ERA and 2.15 WHIP in 20 innings.
