Just started playing league tennis here and they have a pretty good system in place. The mini-winter league just wrapped up with 2 matches per week over a 3 week period. The prices are reasonable if you are Scottsdale resident (usually $35 -$40). The courts here are in good shape, but there are some aging issues with the facility and one dumb decision as well. The full winter league is 10 matches over a 10 week period.
The dumb decision was to put blue lines on the tennis court to appease those old folks who play pickleball. Really, you decided to ruin the courts for 20 senior citizens playing a stupid version of paddle tennis? The other issue is that the tennis balls constantly get lost because the fences are in disrepair on certain courts and balls end up under fences, in restricted areas, etc. Not sure when the place opened, but might be time for a mini-makeover. Otherwise, they do have good and helpful staff.
