Now that performance-enhancing drugs are no longer trendy, the major leagues have decided to increase run scoring by shortening the outfield walls and completely eliminating the annoying three-outs rule. Experience a boom in your offensive firepower with today's deal: for $10, you get one 30-minute batting-cage session (a $23 value), at TPG Baseball & Softball Academy, located just south of Spring Valley.

Use your 30 minutes to perfect the swing of the bat or the snap of the wrist, as the batting tunnel is equipped for machine-assisted or human-assisted pitching. As safety is top priority in the facility, fathers and sons can finally work on their game without ending up as the funniest home-video punch line in America. Choose to rocket your bat toward a planetary softball or take on nature's most elusive orb, the baseball, as you work on home-run swings and humble bunts.

The pitching machines at TPG are designed with authenticity in mind, which means you'll experience simulated ball speed and movement; and though high inside fastballs are rare, charging the pitching robots is strongly discouraged because they are emotionally fragile. Bond with your nieces and nephews ages six and up within the air-conditioned tunnels. Spikes are not allowed, and power hitters must bring their own bats. Call ahead to schedule an appointment.
