Want to watch the American League Championship Series in the best possible quality? You'll need to stream it. Fox Sports is keeping up its recent habits by streaming 2019 ALCS games in 4K HDR through its namesake app and Fox Now. The same caveats still apply. You'll need a 4K-capable Roku device or an Apple TV 4K to watch. And this is technically an upconverted 1080p signal rather than true 4K -- you might not see every dirt smudge on player's uniforms. This could nonetheless be the best view you get, and you can tune into the non-HDR 4K feed using FuboTV and conventional broadcasters.
