The Diamondbacks are increasing capacity at Chase Field from 12,000 to 20,000, and additional tickets for the initial home games of the 2021 season will go on sale at 9 a.m. on Friday.
The decision comes days after Gov. Doug Ducey loosened COVID-19 restrictions in the state.
“As we continue to see the key measurements improve throughout the state and the restrictions lifted on businesses, we feel very comfortable that we can permit additional fans to enjoy D-Backs baseball while still providing a safe and comfortable environment,” Diamondbacks CEO Derrick Hall said. “We will continue to require masks and ask fans to distance appropriately while keeping all other policies in place to start the season.
