MLB.com's Alyson Footer writes that the Astros have once again signed Jason Smith, and optioned Jeff Fulchino to Triple-A Round Rock.
Smith was designated for assignment by the Astros earlier this week, cleared waivers, and elected free agency. However, with Lance Berkman ailing, Houston felt that they needed an extra infielder on the roster.
Smith, 31, was hitless in 21 at-bats with the Astros through 17 games this season. Fulchino, 29, had posted a 5.91 ERA through eight relief appearances, totaling 10.2 innings of work.
