Valentin Jalomo's family said he started showing symptoms around Jan. 4, and on Jan. 8 he was admitted to St. Luke's Hospital with pneumonia and COVID-19.
Jalomo's family said he started feeling better but his health started to decline soon after.
One of the doctors treating Jalomo knew Alex Bregman and told the third baseman about Jalomo's fight. Early Tuesday, the baseball star sent a video to Jalomo and his family to keep fighting.
