If you want to watch things like the featured groups you will need Peacock. Since this is not a PGA event it will not be on PGA live or if you watch the PGA live content on ESPN+ like I do it will not be on there.
USA Network will have the whole first round main broadcast.
Peacock will be the only way to see the second round before 11:00 AM mountain, then NBC has it.
USA will have the third and fourth rounds until 10:00 AM, then NBC has it.
You can watch on USopen.com/the USGA App/NBCSports.com
I am good since I have Peacock, so it is just switching from watching content on ESPN+ to Peacock for me personally.
