Tuesday's and Wednesday's games between the San Francisco Giants and Seattle Mariners have been postponed due to air quality issues in Seattle from mass wildfires in the West Coast.

Both games have been rescheduled for Wednesday and Thursday at the Giants' Oracle Park in San Francisco. The Mariners will still be considered the home team during these games, NBC Sports reported.

According to Airnow.gov, the air quality index in Seattle as of 4 p.m. ET Tuesday was 241, which is considered unhealthy to breathe let alone play a baseball game. The air quality in San Francisco was 68, which is deemed moderate.

Mariners president and COO Kevin Mather said in a statement that the "air quality in Seattle has gotten worse overnight here at T-Mobile Park and it is not clearing at all today."

Mather added that the Mariners "look forward" to returning to Seattle on Friday for their series against the San Diego Padres.

The Oakland Athletics and Mariners played two games Tuesday. Afterward, Athletics' players complained about the hazardous conditions.

Jesus Luzardo, who started that game for the A's, told NBC Sports that he didn't understand why the teams played.

"I'm a healthy 22-year-old, I shouldn't be gasping for air, or missing oxygen when I'm getting to the line," Luzardo said. "I'll leave it at that."

While no plan is set in place, ESPN reports that the Phoenix has emerged as the primary location for any MLB postseason games they need to move due to air-quality problems.

The Giants most recently endured two postponements over the weekend after a coronavirus scare within the organization. However, the MLB concluded that the person who originally tested positive for COVID-19 was clear of the virus and presented no harm to other personnel.

"Following a careful review of all of the details presented in the particular case regarding a San Francisco Giants player that led to the postponements of their road games in San Diego on Friday and Saturday, the committee has determined that the presumptive positive did not represent an actual infection or present a risk to other personnel," MLB said in a statement.
