Yankees fans have seen a lot of Derek Jeter this past week -- the former captain was in attendance for retired number ceremonies for Jorge Posada and Andy Pettitte.

And now they're seeing a lot more as Jeter, who's known for being private, did a new mailbag in the Players' Tribune, the publishing website for athletes he founded after retiring in 2014.

Jeter was the first athlete to get personal in a series aimed at connecting athletes and fans directly through conversation.

The former Yankees shortstop answered all the big questions like what his favorite breakfast cereal is (Frosted Flakes) and what superpower he'd want (invisibility).

Jeter still may be learning the meaning of binge-watching after missing the past 23 years of television, but he's all caught up on one of the Internet's top prank . . . just scroll to the bottom of his mailbag to find his "Twitter" handle.
