Tennis, like fishing, is better with a partner and extremely embarrassing with one's head caught in the net. Snag some friendly competition with today’s Groupon: for $10, you get a three-month membership (a $20 value) to the Tennis Seattle branch of the Tennis League Network, an organization that helps match local tennis lovers with playing partners.

The Tennis League Network operates like a very specific social networking or dating website, but with the sole intention of matching tennis lovers to potential playing partners. See how it works here. The Seattle network alone contains more than 600 members, fingers all twitching toward racket handles in their respective abodes. After registering with the network, you’ll be connected to 20 men and/or women in your area, matched to your specific skill level. The partner program is split into playing regions for Lynnwood, North Seattle, Mid-Seattle, South Seattle, Bellevue-Kirkland, Bothell, and Renton. This pool of individuals allows subscribers to find a dedicated partner with whom to hit the tennis courts or clubs. Start actually playing outdoor or indoor tennis, rather than wistfully thinking about it, with today's deal.
