The Mariners open a three-game series as the home team in San Diego after the set was relocated due to air quality concerns in the Seattle area. The Mariners already had two games against the Giants moved from Seattle to San Francisco this week because of unhealthy air quality from numerous West Coast wildfires. The Padres could be in position to clinch their first playoff berth since 2006 while playing as visitors in their home ballpark. Meanwhile, Braves right-hander Max Fried is set to return from the injured list and resume his bid for an unlikely NL Cy Young Award.
