The last time fans got to go inside Nationals Park for a baseball game was on October 27, 2019 — the fifth game of the World Series. José Andrés threw out the first pitch, and fans booed then-President Donald Trump in his luxury ballpark suite. The Nats lost to the Astros that night, but they went on to win the championship title a few days later in Houston.

On April 1 — more than 17 months since that last game — Nationals Park will reopen to fans.

The D.C. government gave approval to the Nationals Monday to host 5,000 fans during the first games of the season, beginning with the Opening Day matchup against the New York Mets.

D.C. United was approved to host up to 2,000 fans at Audi Field — 10% of the soccer stadium’s capacity — beginning with the team’s first match on April 17 against New York City FC. The Washington Wizards and Capitals have not yet received word on their requests bring fans inside Capital One Arena.

The Nationals are already in talks with the city about increasing capacity for their second slate of home games, beginning April 15, according to a Nationals press release. The current capacity limit only accounts for about 12% of the ballpark’s seats.

“We look forward to increasing our capacity in the coming weeks,” Mark Lerner, the Nationals’ managing principal owner, said in the release. “We cannot wait to have our fans in the stands again, wearing red and cheering on the Nats, as we begin our quest for another World Championship.”

During a Monday press conference on reopening the District, D.C. Mayor Muriel Bowser noted that her team would review its capacity limitations at some point next month.

Just like the vaccine rollout, the ticket-buying process won’t be a free-for-all. Season ticket holders will get the chance to buy tickets first, in order of the holder’s tenure and plan size. The general public will then be able to purchase any remaining tickets.

Tickets will be sold in pods of one to six people, and suites will open with limited capacities. Ticket holders will be required to enter and exit the ballpark from a specific gate noted on their electronic ticket, to facilitate social distancing.

The Nationals have instituted a number of other health and safety measures as part of its reopening agreement with the District and Major League Baseball. Mask-wearing will be required for all fans 2 years and older. Vendors will not accept cash, and Plexiglas barriers have been installed where frequent face-to-face interaction occurs around the park. Hundreds of hand sanitizing stations have been set up throughout the facility.

Nats Park hasn’t sat completely empty since it last hosted ball games. It was repurposed as a voting center in November and as a COVID-19 mass testing site over the winter.

Up 95 in Baltimore, Gov. Larry Hogan said the Orioles could fill Camden Yards to 50% capacity. However, the Orioles plan to welcome only about 11,000 fans — about 25% of the ballpark’s capacity — to start.
