Glasnow sets record with 1,000th K, but exits with lower back pain

6:51 PM UTC

HOUSTON -- entered Wednesday’s series finale against the Houston Astros needing just one strikeout to reach a major career milestone. He didn't make the fans at Daikin Park wait long, picking up his 1,000th career punchout in the first inning by fanning Yordan Alvarez. He's the fastest starting pitcher in Major League history to reach the threshold at just 793 innings.

Unfortunately, his afternoon only lasted two more batters. Glasnow recorded one more strikeout in the first but exited with a trainer before facing a batter in the second inning. He appeared to tweak something while throwing his warm-up pitches, prompting a meeting on the mound and then the early exit with what the team called lower back pain. Jack Dreyer replaced him on the mound.

The injury exit casts a pall over Glasnow's remarkable achievement. The right-hander is in exclusive company as one of fewer than 600 pitchers in Major League history to reach the four-digit strikeout mark. He broke Freddy Peralta's record (804 2/3 innings) for the starting pitcher (minimum 50% of appearances as a starter) to reach 1,000 K's in the fewest innings and joins elite power arms like Robbie Ray, Yu Darvish, and current teammate Blake Snell at the top of the list.

Glasnow surrendered a solo home run to Brice Matthews to lead off the bottom of the first but regrouped to strike out Alvarez -- one of the game’s premier left-handed hitters -- on an 82.3 mph curveball to secure his place in the record books.

The Southern California native entered Wednesday ranking eighth among qualified NL pitchers with a 2.45 ERA and leading the Majors with a 0.70 WHIP. For Glasnow, the road to 1,000 strikeouts has been defined as much by his elite velocity as his resilience. After seasons hampered by elbow and shoulder injuries in 2024 and 2025, the Southern California native has emerged as the durable anchor the Dodgers prioritized when they signed him to a five-year, $136.5 million extension.
