Bryan Morel "Bitsy" Grant Jr. was an American amateur tennis champion. At 5 feet 4 inches (163 cm) and 120 pounds (54 kg), Grant was the smallest American man to win a championship on the international tennis circuit. A right-handed retriever, he was able to beat heavy-hitting greats such as Don Budge and Ellsworth Vines even when playing on grass. His nickname was "Itsy Bitsy the Giant Killer".

John Donald Budge was an American tennis player. He is most famous as the first tennis player — male or female, and still the only American male — to win the Grand Slam, and to win all four Grand Slam events consecutively overall. Budge was the second man to complete the career Grand Slam after Fred Perry, and remains the youngest to achieve the feat. He won ten majors, of which six were Grand Slam events and four Pro Slams, the latter achieved on three different surfaces. Budge is considered to have one of the best backhands in the history of tennis, with most observers rating it better than that of later player Ken Rosewall.
