The White Sox have claimed righty Juan Minaya off waivers from the Astros, Chicago announced. He had been designated for assignment last Tuesday.

The 25-year-old Minaya hasn’t yet reached the majors, and won’t do so immediately for the White Sox — who optioned him to Triple-A. He has scuffled a bit at that level this year, with a 3.91 ERA over 25 1/3 innings, but turned in a strong season at the highest level of the minors in 2015. In 54 2/3 frames last season, Minaya worked to a 2.80 ERA with 9.7 K/9 and 3.5 BB/9.
