Representing Haverford College, G. Diehl Mateer, Jr., won the intercollegiate singles championship in 1948 and 1949. During his senior season, 1950, Mateer was faced with a challenge: compete for his third intercollegiate singles title or compete in the national doubles championship. He chose and won the 1950 doubles championship, which prevented Mateer from becoming the first three-time intercollegiate singles champion had he won.

After college, Mateer continued his phenomenal squash career.
