NEW YORK — The Los Angeles Dodgers’ bullpen faltered late Sunday in a 8-3 defeat to the New York Mets at Citi Field, preventing the Dodgers from completing a series sweep. Reliever Will Klein, who had earlier struck out Mets batter Marcus Semien, gave up a pivotal three-run home run in the seventh inning that shifted momentum decisively in favor of New York.

Klein, who has experienced recent difficulties with his command, faced Semien with a 1-1 count before opting for a fastball. What was intended as an outside pitch instead drifted over the plate, allowing Semien to launch the ball for a three-run homer. Klein reflected on the sequence, observing that had he been able to effectively mix pitches, Semien might have been forced into a less advantageous at-bat. “When you’re ahead and you’re dictating things, that’s a popup, or they have to think about other stuff when I’m throwing off-speed in the zone,” Klein said. He acknowledged that missing his command made it easier for a strong hitter like Semien to capitalize.

The loss came after a successful stretch for the Dodgers, who went 6-3 during their recent East Coast swing. The team secured series victories against the New York Yankees, Philadelphia Phillies, and Mets before Sunday’s setback. Despite the bullpen’s struggles in the final frames, the overall trip was a positive one for the Dodgers as they continue to position themselves in a competitive National League race.

The Mets’ late offensive surge underscored vulnerabilities in Los Angeles’ relief pitching, highlighting the challenges of maintaining consistency over a grueling stretch of games. While the Dodgers’ starting rotation has been a strength throughout the season, the performance of the bullpen remains a crucial factor as the team navigates the playoffs push.

Sunday’s game added to the growing list of closely contested matchups between these two National League contenders, emphasizing the intensity of their rivalry. The Dodgers will look to regroup and address bullpen issues as they prepare for upcoming series and critical stages of the season.
