SEATTLE — The two-game series between the San Francisco Giants and Mariners in Seattle that was scheduled to start Tuesday night was postponed because of poor air quality caused by the West Coast wildfires.

The teams will now play today and Thursday at Oracle Park in San Francisco, with game times to be determined.

The announcement came as forecasters called for smoke to reach very unhealthy levels in Western Washington through at least Thursday.

Both teams had a scheduled day off Thursday that allowed them to avoid playing a doubleheader on Wednesday.

Some players complained about smoky conditions Monday night after the Mariners split a doubleheader with the Oakland Athletics. The smoke level during the games reached a level of very unhealthy on the air quality index, even with the roof closed at T-Mobile Park.

Seattle manager Scott Servais said he thought “visibility and playability” were fine Monday night after the games and that Major League Baseball officials were comfortable with allowing the makeup doubleheader to proceed. But the smoke got worse throughout the evening, seeming to increase when rain moved into the area.

A’s manager Bob Melvin said several players began to complain as the night wore on.

“I’m a healthy 22-year-old. I shouldn’t be gasping for air or missing oxygen. I’ll leave it at that,” said Jesús Luzardo, who started the opener for Oakland.

Neither Servais nor Giants manager Gabe Kapler were immediately available for comment Tuesday.

The area has had unhealthy air quality for about a week after weather patterns have brought smoke from wildfires east of Seattle in Washington, Oregon and California. There are fires burning near San Francisco, too, but the air quality is better.

A Mariners official said smoke is expected to start clearing late Thursday or Friday when they return home for a three-game series with the San Diego Padres, followed by their final three home games with the Houston Astros next Monday through Wednesday.

“We appreciate the Giants’ willingness to work with us on this challenge, and we look forward to returning to T-Mobile Park on Friday to host the Padres,” Mariners President Kevin Mather said.
