Streaming link. I have VPN and use Firefox with UBlock to try to keep the shenanigans to a minimum. You can try the US Open links or the Sky Sports links.
Advice. You can usually always find streams for any sporting events. You just have to use the right search engine. Google, Bing and the mainstream engines filter the streaming sites. Yandex, which is a Russian site, doesn't. I use Yandex when I search for streams for any sporting event. Again, use VPN and some sort of Adblock. Also I use a browser specfically for any shit where I might visit a site which will give my PC AIDS (streams, torrents, and pron). I have Firefox which does not link to any accounts or anything. I have Ublock and other security stuff installed on it. Lastly I have it delete all history when I exit the program.
That may seem like work but it's cheaper than paying for YouTube TV and other streaming shit. I haven't had "cable" TV in 6 years. Never missed any UT games or any sporting events.
