Good troll for your Dodger fan acquaintances: It's alright, Trout didn't hit any either.
At first they think you're being nice....
Trust me it works, already hit my dad and brother with it.
Only way I know how to do it is through the subscription on the MLB at Bat app. Just do the audio subscription. Much cheaper than the video one which is always blacked out. Plus you get your choice in audio streams (home or away) and can listen to any game. But I don't know of a free option. MLB has that on lockdown.
