As you Angel fans know, even though KCOP 13 is carries in HD and broadcast in HD, the Angel games are not in HD on KCOP. But today you are lucky. For those in the LA area and have a provider that carries the MLB Channel, the Angel game is in HD on MLBNet Alternate channel.
If you have DirecTV it is on 214-1. I don't know the channel numbers of the other providers.
