The Pittsburgh Pirates and San Diego Padres wrapped up a three-game series at PNC Park on Thursday despite a 45-minute delay.

The game was delayed because of smoke and poor air quality in Pittsburgh stemming from wildfires in Canada. The air quality index in Pittsburgh was in the "very unhealthy" range Thursday afternoon.

Multiple games were postponed due to poor air quality earlier this month. Major League Baseball has the final say on such matters.

Andrew McCutchen wore a mask on the bases, which is the current recommendation when you go outdoors in Pittsburgh.

"Of course I'm concerned," McCutchen said. "You read the alerts. You read everything they're saying, trying to stay safe from outside. One of the main things is to avoid strenuous activity, and that's what we're doing for three-plus hours out there."
