The Houston Astros have done their due diligence on Cuban infielder Yulieski Gourriel.

Gourriel was recently declared a Major League free agent and is working out privately for teams.

"We've done our homework and we're very well aware of the player and what we believe he's capable of doing," Jeff Luhnow said.

Luhnow didn't say whether the Astros planned to have Gourriel in for a private workout.
