Overview
- Lance McCullers Jr. has been placed on the 15-day injured list with a right foot sprain after making seven starts in his comeback, ending a return that began last month following 2½ years away.
- Rookie right-hander Ryan Gusto, originally slated to start Tuesday, will move up to take McCullers’s turn against the Athletics on Monday.
- In a corresponding move, the Astros recalled right-hander Jason Alexander from Triple-A Sugar Land, where he posted a 1.74 ERA in 20⅔ innings.
- Houston is operating with a six-man rotation through a 13-game stretch without an off day, pushing its pitching depth into action.
- Other season-opening rotation members Ronel Blanco and Hayden Wesneski are out for the year after surgery and Spencer Arrighetti remains sidelined with a broken thumb, exacerbating Houston’s starter shortages.
