Batter up for baseball Down Under? The Oakland Athletics are packing their bats and heading to Las Vegas, with a brand-new ballpark on the horizon. Alas, the design of this new stadium has some fans scratching their heads—and wondering if they accidentally booked a trip to Australia instead.
The proposed arena, designed by Bjarke Ingels Group (BIG), sports a distinctive five-tier roof with a curved design. This feature, inspired by baseball pennants, has sparked comparisons to the world-famous Sydney Opera House.
Ingels sees the crowd’s perceived parallels as a compliment, since Sydney’s landmark, to him, is“one of the most beautiful buildings on Earth.”
While flattered by the association, Ingels assures everyone this is no architectural copycat. Firstly, the Las Vegas stadium is a circular dome, while the Sydney Opera House boasts a rectangular footprint. More importantly, he tells The Athletic that their purposes are vastly different. The A’s ballpark prioritizes climate control, with the layered roof offering shade from the desert sun while letting in natural light for that perfect day game.

Nevertheless, he says he can understand why the ballpark’s “ribbons arch and nest” may spark a sense of familiarity with “a distant Australian cousin,” Ingels adds.
This focus on functionality is key for A’s owner John Fisher. He highlights the roof's ability to shield fans from the Vegas heat while maintaining a bright atmosphere. This “spherical armadillo” design, as Ingels calls it, is an innovative response to the desert environment.
Slated to open in 2028 on the former Tropicana Resort site, the 33,000-seat ballpark will mark a significant change for the Athletics. It also signifies Las Vegas’ growing presence in the major league sports scene, becoming the city's fourth major league franchise. While Oakland fans may be feeling blue, Las Vegas is gearing up for a swing at a whole new ball game.
