Practicing for hours in the batting cage helps sharpen your swing, provides a safe haven from meat-tossing bleacher trolls, and prepares the public for the inevitability of a talented robot athlete overcoming the sport's flesh barrier. Square up your stance in a projectile-sausage-free environment with today's Groupon: for $18, you get a month-long membership and two rounds in the batting cages at Fresno World of Baseball, located off Highway 41 across from Fashion Fair Mall.

The seasoned coaching crew behind Fresno World of Baseball has helped hone hacking slashes and correct poor batting form since 1999, opening their current clean, well-lit, and air-conditioned facility in 2007. They'll supervise your swing time inside any of their nine indoor batting cages, which feature mechanical arm pitching machines spitting rawhide bullets at anywhere from 40 to 70 miles per hour, giving lifelike delivery and simulating in-game at-bats far better than dolphin blowholes. Members enjoy additional benefits throughout the month, such as half off batting cage sessions and two skill enhancing clinics, which improve prospective major leaguers’ hitting, pitching, fielding and bunting (Groupon-thletes choose which they’d like to attend).
