"One of the greatest all-around athletes in Penn history, Don Kellett won nine varsity letters at Pennsylvania, three each in football, basketball and baseball, during the early 1930s.
He led the football team in scoring as a junior and senior, and played on basketball teams with a combined record of 28-9 during his junior and senior years. He captained the basketball team as a senior. In 1934, he batted .459 for the baseball team, still the all-time highest single-season batting average in Pennsylvania baseball records, and hit eight home runs. He played briefly for the Boston Red Sox in the summer of 1934 following his graduation.
Don Kellett was the winner of the Class of 1915 Award as a senior, which is awarded to that member of the senior class who most closely approaches the ideal University of Pennsylvania student-athlete."
