In this day and age, a photo from someone's phone can drastically alter the public perception of an athlete. Johnny Manziel, Greg Oden and many more stars have learned this lesson the hard way.

In light of the ease with which photos can be taken and shared on mobile devices, New York Yankees shortstop Derek Jeter has enacted an unusual but understandable policy at his Tampa mansion.

Jeter, famously private about his personal life, has a "no phones" rule at the enormous estate that is sometimes referred to as St. Jetersburg.

Via the New York Post's Page Six:

Derek Jeter has a strict “no camera or phones” rule when it comes to his sprawling Florida mansion.

We’re told the famously private Yankee has a basket in the foyer of his 30,875-square-foot, multimillion dollar Davis Island home, dubbed by locals “St. Jetersburg.” All guests are expected to plunk down their camera phones before entering his castle.

“He points and says, ‘Phones go there,’ so no one can take pictures inside his house,” says a source.

While this may seem a bit strict, it is a good move by Jeter. Not only does this help him maintain some privacy, it is far more likely that a negative story would emerge from a cell phone photo or video than a positive one. This way Jeter has some control over what comes out of his camp.

It was in Tampa, perhaps even at St. Jetersburg, that Jeter and Yankees owner Hal Steinbrenner negotiated a one-year, $12 million contract that will allow the future Hall of Famer to stay in the Bronx for the 2014 season. Jeter played in only 17 games in 2013 as he recovered from surgery on the ankle he dislocated in the 2012 AL Championship Series.
