Los Angeles Dodgers starting pitcher Tyler Glasnow was removed after pitching one inning against the host Houston Astros on Wednesday with low back pain.

Glasnow allowed a first-inning home run to Brice Matthews and attempted to return in the second. After several warmup pitches, Glasnow, 32, motioned for trainers, who along with manager Dave Roberts removed him from the game.

Glasnow's first-inning strikeout of Yordan Alvarez was the 1,000th of his career.

A 2024 All-Star with Los Angeles, Glasnow was 3-0 with a 2.56 ERA entering his seventh start this season. He signed a five-year, $136.5 million contract before the 2024 season.
