Hazardous air quality caused by thick Canadian wildfire smoke forced the postponement of the Cleveland Guardians game against the Pittsburgh Pirates in Cleveland on Friday night, July 17, 2026.
Haze covered the city for a second straight day, pushing the local air quality index into the very unhealthy range.

Cleveland Clinic urgent care centers and emergency rooms reported a slight uptick in respiratory complications after the smoke arrived.
Local health officials urged residents to limit outdoor exposure and stay inside ventilated buildings to reduce exposure to the hazardous air.
Dr. David Margolius, Cleveland Director of Public Health, emphasized the importance of staying indoors in filtered spaces.
"Any time it's like that, the best advice is to stay inside," said Dr. Margolius.
"But it's got to be inside and a place that has filtration, air conditioning, that's the safest place for folks to be right now."
Margolius reiterated that residents should avoid the outdoor conditions entirely until air quality improves.
"We advise folks to get inside, get into a place that all the windows can be closed," he said.
Despite warnings, fans crowded downtown bars along East Fourth Street after the game was called off.
Many wore protective face masks due to rapidly worsening conditions around the stadium.
Progressive Field employee Colleen noted how quickly the haze blocked visibility across the venue.
"And then before, like, ten minutes before I clocked out, you couldn't even see the other side of the ballpark," she said.
