Going into his 20th season as the Yankees' shortstop, Jeter announced Wednesday that this will be his last.
"For the last 20 years I've been completely focused on two goals: playing my best and helping the Yankees win," Jeter wrote in a letter posted on his Facebook page. "That means that for 365 days a year, my every thought and action were geared toward that goal. It's now time for something new."
He added: "I could not be more sure. I know it in my heart. The 2014 season will be my last year playing professional baseball."
Jeter was the MVP of the 2000 World Series and is a 13-time All-Star. Citing an injury-plagued season from a year ago, he wrote that things that "were always fun had started to become a struggle."
He said he wants to pursue other business and philanthropic interests as well as start a family.
Last season legendary closer
"I want to soak in every moment of every day this year, so I can remember it for the rest of my life," Jeter wrote. "And most importantly, I want to help the Yankees reach our goal of winning another championship."
