"It's a lot of fun to get to the big leagues with guys you came through the minors with," said Cards third baseman Daniel Descalso. "We had success in the minor leagues and we built on that. It's been a lot of fun for us to come up here and contribute."
"It's pretty cool to be up here with guys like Jon Jay and Descalso, and Jaime and Boggs and Motte, a lot of guys who came up together through the system," said Cards Outfielder Allen Craig. "To be playing in important games in October is pretty special."
"It's been great," said Cards centerfielder Jon Jay. "A couple of us came up together and to be in these big spots together it's been awesome. We all support each other and we're looking forward to this game today."
"When I first got the news of coming to the Major Leauges, you know it kind of hit me a little bit, let me understand that all that work I put in back in Springfield, and Memphis, all of it paid off," said Cards Outfielder Adron Chambers.
