Jeff Luhnow feels as though the Astros have vastly improved their farm system in recent years.

"Overall, I'm very happy with the system. I think about what systems would I trade it for and there are very few out there that are obvious. I may trade it for the Cardinals' system," Luhnow said.

"Beyond that, there's not a lot that are obvious that I would say, 'OK. I'll take your system and you take ours.' And that's a good place to be for us."
