"We're talking right now," agent Oscar Suarez said. "We're just trying to figure it out."
Amador was signed last year after he hit 36 home runs for Diablos Rojos del Mexico. He led his team in homers and RBIs, with 121. In 104 games and 449 plate appearances, Amador struck out only 59 times. He played for the Astros in the Arizona Fall League.
A non-roster invitee, Amador was expected to compete for time at first base with Brett Wallace, Jesus Guzman, Jonathan Singleton and Marc Krauss.
