The Astros are calling up Miguel Ullola prior to Sunday’s game against the Tigers.

Kai-Wei Teng will likely be sent down to make room. It’ll be the 24-year-old Ullola’s first stint in the majors. He opened this year going 1-4 with a 6.21 ERA in 10 starts for Triple-A Sugar Land, but he was shifted to the pen at the end of last month and since has a 2.70 ERA and a 16/6 K/BB in 10 innings. He might only be up until Cristian Javier rejoins the rotation next weekend.
