The Rangers last won a series in Houston in July 2018
Marcus Semien hit a grand slam on Sunday night to cap a six-run seventh inning as the Texas Rangers beat the Astros 9-1 for their first series win at Houston in nearly five years.
The Rangers last won a series in Houston in July 2018 when Texas swept the Astros. Since that series, Texas had lost 10 straight series there.
Nathaniel Lowe doubled to lead off the seventh, tying his career high with an 11-game hitting streak. After an error by shortstop Jeremy Peña allowed Adolis García to reach, Josh Jung singled and Jonah Heim drew a bases-loaded walk to score Lowe.
