I've done this in an exhibition match using Roger Federer, because he has great stamina.
As the opponent, I've used my own created player (who was on Level 5 at the time) and had less stamina.
Set the exhibition match to lowest difficulty, only one set with three points or super tie-break and play cool, maybe try not to use too many smash balls as they cost stamina.
Because Roger Federer is a very strong allrounder with a lot of accuracy on the ball, he should be able to stay in "the green" of the stamina bar all the time.
(might help to set the gameplay settings other than "realistic", so the stamina bar below each player is visible)
Just win the match and the achievement is yours.
