"I talked to his agent, Peter Greenberg, earlier in the week, and he informed me that Freddy is expected to be ready to throw in front of scouts soon," Astros general manager Ed Wade told MLB.com on Friday afternoon. "I let him know that we want to be there."
Garcia, 33, hasn't pitched since June 8, 2007, for Philadelphia and has been rehabbing from right shoulder surgery.
The two-time All-Star came up through the Houston organization before the Astros traded him to Seattle on July 31, 1998, along with Carlos Guillen and John Halama, for Randy Johnson.
Garcia won 17 games for the White Sox in 2005 and three more in the postseason that year, including a win against Houston in the World Series.
