2014 USTA League Nationals this weekend - What? I thought they were done?

I recently wrote that 18 & over, 40 & over, and 55 & over Nationals were complete.  So why am I talking about Nationals this weekend?  Because Mixed Nationals are still to be played.

This weekend finds the 18 & over 2.5, 7.0, and 9.0 playing in Tucson while the 40 & over 6.0 and 8.0 are in Surprise.
