After being claimed on waivers from Philadelphia on July 21, Figueroa was 5-4 in 18 appearances with Houston last season. He is 2-0 with a 3.86 ERA in four spring starts.
Figueroa's spot in the rotation was sealed when 20-year-old Jordan Lyles was among seven players sent to their minor league camp Monday.
The other players sent down were pitchers Casey Fien, Fernando Rodriguez, Patrick Urckfitz and Sergio Escalona and outfielders Drew Locke and T.J. Steele.
