Astros manager A.J. Hinch made some changes to his rotation plans leading up to the All-Star break.
Brett Oberholtzer will be recalled from Triple-A Fresno to start Thursday against the Indians.
Lance McCullers, who was scheduled to start Friday against the Rays, has been pushed back to Sunday's series finale. Collin McHugh will now start Friday's series opener and be followed by Dallas Keuchel on Saturday.
Vincent Velasquez was optioned to the minors following his start Tuesday, so he can rest during the All-Star break.
