LOS ANGELES — His start prolonged, the whiffs remained elusive, and the Dodger Stadium crowd became increasingly concerned that Clayton Kershaw might not reach a hallowed milestone in front of them. Finally, with two outs in Wednesday’s sixth inning, at the end of his outing, it happened — an outside-corner slider to freeze Chicago White Sox third baseman Vinny Capra and make Kershaw the 20th member of the 3,000-strikeout club.

Kershaw came off the field and waved his cap to a sold-out crowd that had risen in appreciation. His teammates then greeted him on the field, dispersing hugs before a tribute video played on the Dodger Stadium scoreboard, after which Kershaw spilled out of the dugout to greet the fans once more.

Kershaw, the Los Angeles Dodgers’ longtime ace, is just the fourth lefty to reach 3,000 strikeouts, joining Randy Johnson, Steve Carlton and CC Sabathia. He is one of just five to accumulate that many with one team, along with Walter Johnson, Bob Gibson, Steve Carlton and John Smoltz. The only other active pitchers who reached 3,000 strikeouts are the two who have often been lumped with Kershaw among the greatest pitchers of this era — Justin Verlander and Max Scherzer, the latter of whom reached the milestone as a member of the Dodgers in September 2021.

Kershaw’s first strikeout accounted for the first out of the third inning — immediately after Austin Slater’s two-run homer gave the White Sox a 3-2 lead. Former Dodger Miguel Vargas fell behind in the count, 0-2, becoming the ninth batter to get to two strikes against Kershaw, then swung through a curveball low and away. The next strikeout, No. 2,999 of his career, came on his season-high-tying 92nd pitch of the night — a curveball that landed well in front of home plate and induced a swing and miss of Lenyn Sosa to end the fifth inning.

Dodgers manager Dave Roberts did not even look at Kershaw as he made his way back into the dugout, a clear sign that he would not be taken out. The crowd erupted as Kershaw took the mound for the start of the sixth inning. Mike Tauchman grounded out, Michael A. Taylor hit a double, then was caught stealing on a play that prompted Dodgers third baseman Max Muncy to come down hard on his left knee, forcing him to be helped off the field.

The mood suddenly turned somber at Dodger Stadium. Then, four pitches later, came elation.

Kershaw reached 3,000 strikeouts in 2,787⅓ innings, making him the fourth-fastest to reach the mark, according to research from the Elias Sports Bureau. The only ones who got there with fewer innings were Johnson (2,470⅔), Scherzer (2,516) and Pedro Martinez (2,647⅔).

Before the game, Roberts called the 3,000-strikeout milestone “the last box” of a Hall of Fame career — one whose spot in Cooperstown had already been cemented by three Cy Young Awards, 10 All-Star Games, an MVP, five ERA titles and more than 200 wins.

Kershaw’s 2.51 ERA is the lowest in the Live Ball era (since 1920) among those with at least 1,500 innings, even though Kershaw has nearly doubled that. He was a force early, averaging 200 innings and 218 strikeouts per season from 2010 to 2019. And he was a wonder late, finding ways to continually keep opposing lineups in check with his body aching and his fastball down into the high 80s.

Kershaw went on the injured list at least once every year from 2016 to 2024. A foot injury made him a spectator last October, when the Dodgers claimed their second championship in five years. The following month, Kershaw underwent surgery to repair a torn meniscus in his left knee and a ruptured plantar plate in his left big toe, then re-signed with the Dodgers and joined the rotation in mid-May. He allowed five runs in four innings in his debut but went 4-0 with a 2.08 ERA in his next seven starts, stabilizing a shorthanded rotation that remains without Blake Snell, Tyler Glasnow, Roki Sasaki and Tony Gonsolin.

Since the start of 2021, Kershaw has somehow managed to put up the third-lowest ERA among those with at least 400 innings, behind only Shohei Ohtani and Max Fried.
