Smoke from wildfires in Canada is causing problems across major northern U.S. cities. Hazardous air quality alerts have been issued in 15 states, affecting over 100 million people. Health experts warn about risks from fine particulate matter, which can worsen asthma, heart conditions, and increase cancer risks.
Various sporting events have faced disruptions due to poor air quality from these wildfires, particularly in the Midwest and Northeast. On Thursday, a Major League Soccer game was postponed, and a Major League Baseball (MLB) game in Philadelphia was moved up an hour.
With the MLB season now unofficially in its second half, several games were planned in affected areas on Friday, requiring logistical changes.

Here are the key updates from these events:
- Los Angeles Dodgers @ New York Yankees, 7:05 p.m. ET: Although New York saw double the air quality issues in 2023, conditions improved throughout the day, allowing the game to proceed.
- Chicago White Sox @ Toronto Blue Jays, 7:15 p.m. ET: Despite concerns over hazardous air levels, Toronto’s air improved to a ‘low health risk’ by Friday afternoon. The Blue Jays closed Rogers Centre’s retractable roof to maintain air quality.
- Miami Marlins @ Milwaukee Brewers, 7:40 p.m. ET: Milwaukee’s air quality improved significantly by late afternoon. The Brewers have similar roof regulations as the Blue Jays, allowing fans to change tickets if needed.
- Pittsburgh Pirates @ Cleveland Guardians, 7:10 p.m. ET: The Guardians postponed their game until Saturday due to Cleveland’s ‘very unhealthy’ air quality. Fans unable to attend the makeup can exchange tickets for future games.
- Minnesota Twins @ Chicago Cubs, 8:05 p.m. ET: Chicago decided to continue the game despite earlier ‘very unhealthy’ air quality readings.
Fans and officials are closely monitoring ongoing air quality issues and adjusting plans as needed to ensure public safety and enjoyment of the sporting events.
