explains the historical name tee boxes for what is today known as teeing ground. The earliest golf tees rested flat on the ground and had a raised portion to prop up the ball. The first patent for this kind of tee is dated 1889, and was issued to Scotsmen William Bloxsom and Arthur Douglas. The first known tee to pierce the ground was a rubber-topped peg sold commercially as the "Perfectum." This was patented in 1892 by Percy Ellis of England. In 1899, an African-American dentist, Dr. George Franklin Grant, obtained a patent for an "improved golf tee". This tee consisted of a wood cone with a rubber sleeve to support the ball, but it is not known to have ever been marketed. These and other variations failed to catch on, as most golfers—whether because of tradition, habit, or concerns about the rules—continued using heaps of sand. It took a strong marketing effort by Dr. William Lowell, Sr. in the 1920s to bring manufactured tees into widespread use. Sales of his "Reddy Tee," a simple wooden peg with a flared top, took off after Lowell hired professional golfers Walter Hagen and Joe Kirkwood, Sr. to promote the product during exhibition matches. It was copied around the world, and remains the most common type of golf tee. Tee-ball tee Tee-ball is based on baseball, with the main difference being the use of a tee in the place of a pitcher. Much larger than a golf tee, the tee-ball tee is a durable rubber stand attached to the home plate which supports the baseball at a suitable height for the batter to hit. It is adjustable to allow for variations in batter height. Baseball tee While a tee for baseball is very similar to a tee in tee-ball, the uses for the tee may differ. In baseball, a tee is used as a training device. This allows the hitter to simulate a pitch that will be thrown in many different locations. Using a tee, the hitter can set up a pitch that may be thrown inside, down the middle, and outside as well as high and low. Unlike tee-ball, where the ball is sitting on the tee, in baseball the pitch is being thrown by another player, resulting in the ball crossing the plate in several different areas. As a batter, using a tee as a training aid will help the hitter
