You don't have to travel to a galaxy far, far away to see Star Wars characters on a baseball diamond.

The Durham Bulls, the Triple-A affiliate of the Tampa Bay Rays, announced the team will wear jerseys -- meant to look like the Star Wars robot R2-D2 -- on May 4. The team will also auction off those jerseys to benefit the Autism Society of North Carolina.

May 4 has become an unofficial Star Wars holiday as the date (May the Fourth) resembles the series' iconic line, "May the force be with you."

The Bulls aren't the first team to don Star Wars-inspired jerseys.

Last Monday, minor league hockey team the Tulsa Oilers wore jerseys that included the faces of Star Wars creator George Lucas, Luke Skywalker and Princess Leia. The U.S. Under-18 men's national hockey team wore jerseys featuring Darth Vader in January. And last year, the Toledo Mud Hens (the Detroit Tigers' Triple-A team) wore jerseys that resembled Chewbacca.

The San Francisco Giants have had Star Wars Day for years. This year, the team will give away an R2-D2 beanie hat.
