Touted infield prospect Cam Smith will be among the non-roster players invited to major-league spring training, the Houston Astros announced Friday. Smith, 21, was acquired by the Astros in the trade of Kyle Tucker to the Chicago Cubs this offseason and immediately became Houston’s top-rated prospect by some outside evaluations.

Miguel Castro could compete for a middle relief role for the Houston Astros, who should have multiple spots up for grabs in spring training.
