Baseball is a distinctly American sport, much like competitive eating and filing lawsuits. Practice suing skills with today's Groupon: for $30, you get a private 30-minute hitting lesson (a $50 value) and 20 batting-cage tokens (a $20 value) at D-Bat Keller in Fort Worth (a $70 total value).

D-Bat Keller solidifies swings of baseball and softball sluggers within its brightly lit indoor batting-cage facility. A team of well-honed hardballers leads private half-hour lessons that guide burgeoning athletes through tactical improvements involving swing mechanics, throwing and fielding abilities, and how to chew an entire pack of bubble gum at once. Parents play an equally pivotal role during lessons, providing feedback on their child's progress when away from D-Bat's friendly confines. Follow up instructional stints with 20 rounds of baseball or softball tosses inside the climate-controlled cages, or solicit ongoing advice from the staff of former college and professional ballplayers. D-Bat's instructors bring big-league hitting and fielding experience via the Texas Rangers and Milwaukee Brewers, as well as cooking tips on how to prepare an Englishman from the San Francisco Giants. Advanced registration for lessons is required.
