A man seated behind home plate who was treated by emergency medical personnel and carried out of the stands during the Diamondbacks’ game against the San Francisco Giants on Saturday night at Chase Field appears to be doing better.

The man, a 56-year-old former minor league pitcher, was at the game as a guest of Giants' pitching coach Curt Young, who told a San Francisco Chronicle reporter that his friend is alert and recovering at a local hospital. The man's name has not been released by medical professionals.

As of Sunday morning, the man had been removed from critical care but was still recovering at the hospital, the man's son told The Republic.

In the bottom of the second inning, first responders performed CPR on the man as play continued on the field. Multiple witnesses said he stopped breathing.

Danielle Campos, a 35-year-old nurse in Phoenix, said she was the first to perform CPR after realizing the man who was seated in front of her had become unresponsive.

Campos said she noticed the man was slumped over in his seat and appeared to be perspiring heavily. When the man's companion tried to shake him, Campos said, he was unresponsive and other folks in the section helped to get the man on the ground.

The man received treatment for several minutes. After the second inning ended, players from both teams looked on, delaying the start of the third inning until the man was carried up and out of the section on a backboard while receiving oxygen.

Campos said she was later informed by a medical staff member that the man was alive and breathing on his own at a nearby hospital.

Fire and law enforcement officials referred requests for information to American Medical Response (AMR), which did not respond to inquiries.
