2017 draftees C Nathan Perry (5th) and RHP Matthew Merrill (37th) along with NDFA Tanner Duncan assigned to the club.
Also being brought up from the DSL club is 21-year old RHP Ronaldo Marrero. He was an infielder in the Phillies organization who was released by them last August. He was signed by the Astros last month and converted to pitcher. In 18 IP in the Dominican, he had a 1.47 ERA and 0.71 WHIP with 13 whiffs vs 3 walks.
Merrill, Duncan and Marrero all saw their first action in today's game. And it was the kid from the club team with the best performance of any Astros' pitcher on the day--retired all 6 batters he faced, 2 by strikeout.
