Easily missed behind the Pharr Tennis Center, Patterson is a cute little park with a playscape/pool that look like it would be great fun to bring kiddos to, if you had any. I was there primarily for the tennis courts, and that side was pretty much all I saw, but there is also apparently a volleyball court, basketball courts, & picnicking areas/bbq pits.
The park (or at least the tennis courts) is far enough back from Airport that it had the nice secluded feel that you want from a park, and there wasn't too much noise. The courts are unsurfaced concrete, though, which doesn't make for the best playing. There aren't as many cracks as the courts on Enfield, but I guess if you're interested in a serious game, you can always pay to use the Pharr. Another thing is that, like many park courts, they're open-sided, so if you've got some out of control hitters, be prepared to chase down some errant tennis balls (and park farther off).
Casual hitting or service practice isn't so bad on concrete, and the nets were in pretty good condition, so Patterson is an OK option for tennis. Though I certainly wouldn't mind if they'd surface it. But on the plus side, since people don't generally like concrete courts, that means there's less or no wait during prime after-work hours.
