I played an interesting practice set the other day versus a teammate on my 3.5 men's USTA team. I served first and got broken, but broke back the next game. He broke me again, and I quickly returned the favor. It went on like this for the first seven games. He held serve in the 8th game to take a commanding 5-3 lead, and of course broke me again to close out the set. I had a similar match last summer, trading breaks until the 9th game before I pulled away. Have you ever played a set where neither player held serve?
