Howie Kendrick is retiring from major league baseball after 15 seasons. His long career included two unforgettable post-season home runs that paved the way to the Nationals’ first-ever World Series championship in 2019.

Kendrick, who, at age 37 was one of the sport’s senior citizens, announced his decision on Instagram yesterday.

“I will be forever grateful for the many life lessons baseball has taught me on this 32 yr journey,” he wrote.

Kendrick thanked many people in the post, first among them his grandmother Ruth Woods, “who laid the ground work and introduced me to the game of baseball.” He also thanked his wife and two sons, whom he vowed to spend more time with.

“I’m looking forward to being a constant pain in your butt day in and day out,” Kendrick wrote.

Kendrick won many Washingtonians’ hearts in the National League Division Series in October 2019, when he hit a 10th-inning grand slam, breaking a tie with the Los Angeles Dodgers and sending the Nationals to the championship series for the first time.

Weeks later, Kendrick did it again. In the seventh inning of the seventh game of the World Series, he hit a two-run homer, putting the Nationals in the lead against the Houston Astros.

“I feel as though I’d been a National my whole career and the wild, humbling and crazy ride we had in 2019 truly culminated everything I’d learned in my career, and we all became World Champions,” Kendrick wrote in his Instagram post.

“For now, it’s time to drop the mic and enter a new stage of my life.”
