HEATH - The local non-profit group Rockwall Tennis Unlimited is hosting an open tennis tournament on June 17 at Rockwall-Heath High School.

The event is in conjunction with the United States Tennis Association’s declaring June as national tennis month

The event will be held adults and juniors on from 8:30 a.m. to 3:30 p.m. The tournament fee is $10 for RTU members and $15 for non-members.

“Each team will consist of three women and three men,” said RTU President J.R. Rahmanzadeh.“A team match will consist of one women’s double, one mixed double, and one men’s double. Each team will play a round robin in their division (according to the rating of their players).

“Matches are eight or 10 game pro sets, depending on the number of teams in the division. If there are eight or more teams in a division, the division will be split into two groups.

“Then the two top teams in each group will advance to the playoffs. Prizes are awarded to the top two teams in each division.”

RTU will be offering a new exercise-based tennis program.

“Tennis Industry Association, which is part of USTA has requested that we provide a newly created ‘cardio tennis’ for at least four sessions, free of charge to the public,” Rahmanzadeh said.

“Cardio tennis is first and foremost, a great fitness activity. People of all abilities can participate in cardio tennis at the same time. It's a great way to meet people and have fun while working out,” he said.
