After centuries of ridicule, baseball players have finally convinced professional crotchety-old-man Andy Rooney that running after flying orbs isn’t just for men in black or Harry Potter. Celebrate baseball's newfound acceptance among Americans with today’s Groupon. For $22, you get a field-box ticket to a Houston Astros game (a $39 value). You'll have your choice of seeing the Astros play the Florida Marlins on Tuesday, April 20, at 7:05 p.m. or the San Diego Padres on Saturday, May 8, at 6:05 p.m. When you click "Buy" you'll be redirected to Ticketmaster.com to complete your transaction.

As the new season dawns, the Astros are led by their big-swinging left fielder Carlos Lee, who posted a .300 average and 102 RBIs in 2009, as well as left-handed hurler Wandy Rodriguez, who fanned 193 batters in 205.2 innings while maintaining a trim 3.02 ERA last year. Whatever the season holds, fans will be able to experience world-class athleticism and outfield-wall-scaling robberies in one of the nation's finest home-run habitats and fastball farms—Minute Maid Park. Built in 2000, the park boasts a natural grass outdoor field; a 242-foot-high retractable roof; a distinct, pole-obstructed center field; and a troll-guarded infield. Field-box seating treats you to some of the best seats in the house, as well as unobstructed views of relievers forming sweat-filled moats around the pitching mound and managers hand-signaling Chinese delivery-menu items to base runners.

Spring doesn’t truly start until the first ball game of the season, just as summer doesn't truly start until things start exploding constantly in every movie that comes out. Today's Groupon lets you cheer on deft dexterity and impressive leaping without having to spend a week living in jungle canopy with Richard Simmons.

Note on Ticketmaster fees: You'll get the same percentage off the convenience charge; but you'll still need to pay the full Ticketmaster processing fee, the optional printing-at-home fee, and tax. Ain't no discounts on tax.
