The Houston Astros are facing a rash of injuries to their starting rotation, with Hunter Brown, Cristian Javier, and Taatsuya Imai all going down during a recent road trip. In response, the team is predicted to call up top pitching prospect Miguel Ullola to help bolster the staff.

Why it matters

The Astros have built a reputation for developing elite pitching talent, and Ullola's electric fastball and strong minor league performance could provide a much-needed boost to the rotation as the team looks to get back on track after a tough stretch.

The details

According to a report from Bleacher Report's Joel Reuter, the Astros are expected to promote the 23-year-old Ullola, who has a 65-grade fastball that touches 97 mph, to the major league roster. Ullola has posted a 1.86 ERA in two starts in the minors this season and had a 3.88 ERA in 23 starts last year.

  • The Astros have lost five straight games and six of their last seven on the road.
  • Hunter Brown, Cristian Javier, and Taatsuya Imai have all sustained injuries to the Astros' starting rotation during this recent road trip.
