[4][5] Baltimore City College began competing against other secondary schools in 1919 when it was invited to join the Maryland Scholastic Association (MSA) as a founding member.
The current City College varsity athletic program consists of 18 sports: six for boys, eight for girls, and five coeducational teams.
Since winning its first championships (baseball and ice hockey) in 1903, the Knights' athletic success has spanned every sport offered by the school.
Though it no longer sponsors bowling, fencing, golf, and ice hockey, City has won titles in 20 different sports in its history.
[9] The most successful head coach in school history was George Howard "Jerry" Phipps, who led the Knights to a record of 133–27, four Maryland Scholastic Association (MSA) championships, and a streak of forty straight games without a loss spanning two seasons between 1960 and 1968.
[17] The Baltimore City College football program began in the mid-1870s, and has won more than 20 MSA A-Conference and MPSSAA championships in its history.
[3] The program began competing against other high schools at the beginning of the 20th century, and has held since 1941 the record for the longest streak of games played without a loss in MSA and MPSSAA history.
[18] Harry Lawrence, who guided the Knights to a 38-game undefeated streak between 1936 and 1940 (including 35 wins, three ties, and four MSA championships), remains City College's most successful head football coach.
Young left the program after the 1967 season to join the National Football League as an offensive line coach for the Baltimore Colts and would later become the general manager of the New York Giants.
By the 1930s a "Peace Pact" was sworn annually and signed by student government leaders of both schools before the cameras of the press in the Mayor's Ceremonial Office in City Hall.
Several student disturbances at games or on transit buses afterwards in the late-1960s and early-1970s threatened to put an end to the athletic tradition reflecting the tense tenor of the times, but goodwill eventually prevailed again by the quieter 1980s.
That evening's TV news and sports casts led off with the scores and highlights of "The Game" and half-time shows and parades.
City College won the 127th meeting in 2015 by routing Poly by a final score of 42–6, the school's fourth consecutive victory in the series.
