From the press release published last Wednesday:

Among the artifacts recently accessioned into the Museum’s permanent collection is an authenticated iPhone 17 Pro used during an Apple TV broadcast of Friday Night Baseball. The Sept. 26, 2025 matchup between the Boston Red Sox and Detroit Tigers incorporated live game footage from four devices, marking the first use of an iPhone as a primary camera in a professional sports broadcast.

I can see this becoming a trend for a variety of sports just given the always-on connectivity of the iPhone paired with industry leading video and audio quality.
