Thursday’s game between the White Sox and Blue Jays was delayed after a fan went into cardiac arrest down the left-field line at Rogers Centre. He was later pronounced dead at the hospital.

According to “the man in white,” who was tweeting from the game, a fan performed CPR on the ailing man first and then medics took over after reaching his location. Medics continued to perform CPR as he was carted off the field, and the game resumed after he was taken off. City-TV reported after the game that he died in the hospital.

The White Sox were on the field before the game was delayed.

“It was not a good sight,” White Sox third baseman Kevin Youkilis said afterwards. “I saw some medics jump out around the dugout and run over. Then I saw a doctor or whoever was going, just pushing on the chest over and over and over. I thought maybe they were reviving him and then they next thing you know, they kept going and going.”

The identity of the man has yet to be released.
