Whats your coverage like in the UK? It's annoying here with only 1 channel and no choice of match as you usually don't get to see the whole of the match you want. Didn't get the first set here as we still had the Wawrinka match and joined at the start of the 1st set tiebreak when that finished. Was praying Wawrinka would win the 4th set tiebreak as if it went to a 5th set we'd have missed most of the rest of the match. Was better in the Aus Open this year when we managed to get 2 channels so had a Rod Laver channel and another showing usually Hisense.
I don't have Sky but do have Tennis TV (about £85 per year) which isn't showing anything from US Open, also Eurosport Player (£1.99 per month) which is showing Armstrong matches this evening for some reason. I do get my money's worth on other tournaments, but for US Open it has mostly been dodgy livestreams (for which I'm very grateful), plus BBC Radio 5 live sports extra at times.
