Hollow Rock Open

Hollow Rock Open. Thirty-seven draws across singles and doubles on green clay at Hollow Rock Racquet Club in Durham, running through the first long weekend of May. Level 5 competition means you're playing against players who've put in real time, so expect consistent volleys and someone who can construct a point. Entry runs $50 to $60 per event, and you get a four-day stretch to dial in your game before the summer heat sets in.
