Watch and listen ONLINE Cubs vs.Astros LIVE Stream HERE : This weekend series pits two of the worst teams in the entire major leagues in what will be an inter-league series. The Astros have some momentum as they are coming off an extra inning walk-off homerun by Carlos Pena in a 7-4 victory over the Milwaukee Brewers.

"What a ballgame," Pena told MLB.com. "What a great home-stand we just had. We were in every single game and won most of them. To end the home-stand in such a way like this is very powerful. It gives us a lot of momentum going forward."

The Cubs are coming off a loss in which the team continued its struggles to score runs. Chicago managed one run and that helped the team stay in the cellar of the NL Central.

"It's tough, but I keep my mind positive," Castro told MLB.com. "There's four months left -- just keep aggressive and keep playing hard. I know I'm working hard every day. When I get out [of this], I'll be good for the rest of the season. It helps me, too, because, when I get out of this, I know if it happens again, I know I have my mind strong and I can get out of it."
