Baseball is a game of superstitions: hitters don’t wash helmets while on a streak, and managers don’t brush their teeth for weeks after a great argument with an umpire. Hone your own diamond rituals with today’s Groupon to D-BAT, with locations in Lewisville or Rowlett. Choose between the following options:

• For $10, you get 20 batting-cage tokens (a $20 value).
• For $20, you get a one-hour batting-cage rental (up to a $50 value).<p>

D-BAT’s climate-controlled facilities house instructional cages that can hold dual baseball/softball machines to etch players’ muscle memory with sound mechanics without the pressures of game day. Founded by former collegiate and pro-ball players, D-BAT caters to the needs of diamond dusters who are still searching for a cool nickname such as Babe, Catfish, or Jeff. With 20 tokens or a one-hour rental, power and contact hitters can tramp over the new, artificially verdant field turf and hunker over home plate for fast and slow pitches. The machines’ varying speeds and locations simulate live pitches, and consistent repetition slowly whittles away a swing’s jerks, hitches, and poor manners until it is one smooth and powerful transfer of power. A pro shop stocks Easton and Rawlings lines, equipping players for their latest battle with an orb-hurling automaton.
