A tennis garment of fabric material and sewn construction has a front panel sewn to a rear panel with a waistband encircling the garment. A ball securing sleeve is aligned with, and joined to, the rear waistband portion at left, central, and right mutual locations, thereby establishing two ball securing sleeves into which a tennis ball may be inserted from above or below the sleeve. Once inserted, the ball is held in place by opposing upper and lower elastic bands within upper and lower hems of the sleeves. When desired, the ball may be withdrawn from the sleeves by upward or downward movement relative to the sleeves.
