I have Chromecast, use it for YouTube TV. There was no way (that I saw) to cast the practice last night via Chromecast.
True the primary purpose for the chromecast device is to use the built in streaming apps, but you can also 'cast' to your TV through the chrome cast device via your WiFi network - anything your phone is displaying such as vacation photos, birthday videos, or any streaming video you can access. This is true for android phones, I am not 100% sure about Apple.
