Former New York Yankees legend and generational shortstop Derek Jeter has taken up golf since his retirement from Major League Baseball back in 2014. This is similar to many retired professional athletes, and it keeps these players in touch post-retirement.Jeter had also just joined social media, creating both Twitter and Instagram accounts recently. This was long-awaited, because Jeter had never had his own personal account on social media. Fans were wondering what The Captain was up to after his career with the New York Yankees.Derek Jeter@derekjeterLooks like I’ve officially run out of excuses. twitter.com/jeffguity/stat…Jeffrey Guity@jeffguityDerek Jeter has no excuse not to have a Twitter account by now24591612877Derek Jeter has no excuse not to have a Twitter account by nowLooks like I’ve officially run out of excuses. twitter.com/jeffguity/stat…"Looks like I've officially run out of excuses." - Derek JeterJeter joined Twitter and Instagram for multiple reasons, but mainly because most other celebrities have social media accounts.

Sabathia and Andruw Jones, during a golf tournament. In the picture, the three are smiling and laughing, with Jeter standing near the the others' golf cart.

Apparently, according to Jeter, he did not perform that well at his own tournament. In his tweet above, he said he hopes to do better at the upcoming American Family Championship than he did at his event.It is nice to see Jeter active on social media after all this time. Jeter took over an entire generation at shortstop and inspired thousands of young athletes to play the game. Now post-retirement, it is nice to see him, along with other former players, interacting with each other on social media.
