Over the past week, chances are either you or someone very close to you has been hunting Pokemon.

As the mobile game Pokemon Go continues to swell in popularity (an estimated 7.5 million downloads so far), baseball teams across the country are taking full advantage.

Take for example the Durham Bulls, the Triple-A affiliate for the Tampa Bay Rays, who are opening up their park on Tuesday to allow fans to play the game.

For a $5 entry fee (proceeds go to a pet adoption charity), fans will be allowed to roam the stadium in search of Bulbasaur, Krabby, Weedle and all the creatures of the Pokemon universe.

Using the camera on your mobile device, the game displays various characters that appear to be in your proximity. When you see one, it's your job to shoot a Poke ball at it to add it to your Pokedex.

It may sound silly, but there's no doubting the hysteria surrounding it. Major League Baseball parks certainly seem to be fertile hunting grounds:

Don't be surprised if you see fans collecting Pokemon in the stands during this week's All-Star festivities in San Diego.
