UTR Division Information

The 2023 CSO will utilize UTR ratings instead of NTRP Ratings. 

Men's Divisions

UTR 1-3 | UTR 3-5 | UTR 5-6.5 | UTR 6.5-8 | UTR 8-10

Women's Divisions

UTR 1-3 | UTR 3-5 | UTR 5-7

UTR 1-3 | UTR 3-5 | UTR 5-7 | UTR 6-8

The CSO Tournament Committee strongly encourages all participants to play at their UTR level. However, 'playing up' to a higher level is allowed. You will not be allowed to play down. For example, if you are a male rated 6.65 you will not be allowed to enter the UTR 5-6.5 division

Your UTR Rating is fluid & adjusts based on all results.

PLEASE NOTE: Your UTR Rating at the tournament deadline will be used to decided what division you play in.

Doubles Divisions: Both players must not exceed the maximum UTR for that division. It is NOT AN AVERAGE.

A lot of time, effort & discussions with CSO & UTR representatives went in to finalizing our UTR divisions. If you have any further questions please reach out to CSO Tournament director Alex Dove via email.

You do not need a UTR a membership to participate in a UTR event - every tennis player already has a FREE UTR account to view your rating. If you are interested in learning more about UTR, look them up directly at

Meet Tournament Director: Alex Dove

Meet Alex Dove

Alex is originally from Kent, England. He spent his junior years competing in several junior sports (tennis, 'football', cricket & rugby) but was always drawn to tennis.

He was captain of his high school varsity team and went on to play college tennis at the University of Liverpool where he graduated with a Bachelor of Arts in Business Economics. Alex first started teaching tennis while at Liverpool, and upon graduation Alex moved to America and hasn't looked back since.

He learned his trade under Patrick Tauma (former coach of Naomi Osaka) as the Head Junior Professional of ISP Academy in Boca Raton, FL. He then spent 6 years in the Washington DC area at the Chevy Chase Club where he discovered another passion - Platform Tennis (known as 'paddle'). Alex enjoys teaching and competing in national tournaments around the country finishing in the top 10 at this year's mixed nationals.

Alex and his wife Jackie moved to Denver three years ago. He has been the Assistant Director of Racquet Sports at Arapahoe Tennis Club & recently accepted the position as Director of Racquets at Club Greenwood.

Aside from work, Alex loves just about any English sport (don't say soccer), travel, skiing and taking their pup on some long hikes!
