In an effort to decrease rubbernecking on the highway, government officials have issued a statewide ban on tennis play both inside of and on top of flaming accident sites. Outsmart Uncle Sam's crackdown on tennis spectatorship with today's deal: for $20, you get one ticket to watch the Philadelphia Freedoms in an upcoming World TeamTennis match at The Pavilion at Villanova University (a $40 value). Your Groupon is good for a seat in rows G–M at one of the following matches:

• Philadelphia Freedoms vs. New York Sportimes at 7 p.m. on Friday, July 9, 2010
• Philadelphia Freedoms vs. Boston Lobsters at 7 p.m. on Monday, July 12, 2010

As the only professional coed team sport in the continental United States, Alaska, and Hawaii, World TeamTennis provides tennis enthusiasts with an adventurous approach to match play. A single match consists of two teams made up of high-ranking men's and women's professionals. These four-player teams (two men and two women) battle one another across a five-set gauntlet—the one-on-one onslaught of men's and women's singles, the low-five-laden lusciousness of men's and women's doubles, and the gender-juxtaposed jubilation of mixed doubles. Whoever wins the majority takes home bragging rights and, possibly, temporary immortality. This year's Philadelphia Freedoms roster features fast-serving superstar Andy Roddick alongside pros such as Ramon Delgado and Courtney Nagle.

World TeamTennis provides a handy opportunity for tennis fans to catch a wide range of playing formats and professional talent all on one court. If you opt to attend the match on Friday, July 9, you'll have prime seats to catch Ashley Harkleroad—the first professional tennis player to demonstrate her form in the pages of Playboy magazine—and if you decide to serve up seats to yourself on Monday, July 12, round up the family to partake in Billie Jean King's kids night.
