The lightweight and small tee-up-device is attached to a golf club shaft or a golf club head for the purpose of picking-up and teeing-up balls while practicing at a driving range or on a putting green, or playing a round at a golf course. The device allows a golfer to practice hitting balls off a tee without: bending over, squatting down, moving his feet, shifting his natural stance, releasing or adjusting his natural grip on the golf club, altering his natural swing, or interfering with the natural striking of the teed-up golf ball. The device has a seat (110) to hold the ball, a gap (118) in the seat to allow the device to withdraw from the tee, tips (114) to help hold the ball and help guide the device when picking-up the ball, a mount (120) and accessories (123) to attach the device to the club. The seat is preferably C-shaped with diameter slightly less than the diameter of a ball. The device is made of a material rigid enough to carry the ball when the ball sits in the C-shape. This material also has enough flexibility so that the ball can be easily forced through the C-shape when the ball is picked-up by the push-through method. The tips are curved to prevent sticking in the ground and flared to help guide the ball onto the seat when the ball is picked-up by the scoop-method. The C-shape exposes the bottom of the ball so that the ball can be placed on the tee. The gap in the C-shape of the seat is large enough to allow the tee to pass through the gap after the ball has been placed on the tee.
