In 1946, O'Connell signed with the Brooklyn Wanderers before moving to the New York Americans in 1948. In 1947, he scored sixteen goals in fifteen games with the Wanderers. O'Connell experienced his greatest personal success when he was named the league MVP in both 1948 and 1949. In 1950, he was with the U.S. Army, fighting in the Korean War. After returning to the U.S., he rejoined the Americans which won the 1954 ASL and National Challenge Cup titles. In 1956, the Americans merged with Brooklyn Hakoah to form New York Hakoah.
