World Series live stream: Watch online free Red Sox vs Cardinals game 4 Sunday 8:00 ET as St. Louis leads series 2-1 with Boston looking to tie it up. 

Watch the free live stream online of the World Series that has become an interesting one. The Red Sox vs Cardinals series looks to follow the dramatics of game 3 that might be talked about for years.

Coming off a victory of game 3 of the World Series vs the Red Sox, the Cardinals walk-off win was controversial to say the least. After throwing a runner out at home, catcher Jarrod Saltalamacchia threw it to third where there was runners-interference on third basemen Will Middlebrooks. Watch the free live stream as Boston looks to rebound.

Saltalamacchia told MLB.com that this loss, as difficult as it was, won't linger.

"Obviously, we're mad right now, Saltalamacchia said. "But you have to have that ability to walk out of the clubhouse and forget about it. You go home. You have a family. It's a lesson. It's a lesson you go through. But I think we'll be all right. That's the way it goes, man. That's part of the game. Nothing is going to be handed to us."

On the hill will be Clay Bucholz for Boston and Lance Lynn for St. Louis. . The right-hander has logged two wins in the postseason despite surrendering seven earned runs in 11 2/3 innings pitched (two starts, one relief appearance) as he is pitching on 11 days of rest. Bucholz has his struggles as well, pitching with a 5.40 ERA in three starts.

"Every time I pitch, the last thing on my mind is to preserve anything," he said. "The one thing I have is to go out and compete: Go out there for as long as [Farrell] wants to leave me out there and give the team a chance to win to the best of my ability. I'm not 100 percent, [but] it's going to be my first World Series experience, being on the field. And I think that just the environment, the crowd, the adrenaline, that's going to help me out."
