Waldman is considered a pioneer in the male-dominated field of sports broadcasting. She is the third woman in Major League Baseball history to serve as a full-time color commentator on a regular basis, after Betty Caywood in 1964 and Mary Shane in 1977. In the mid-1990s, she was a play-by-play announcer for the Yankees' local TV broadcasts on WPIX, which made her the second woman to serve in that capacity on TV for a major league team, after Gayle Gardner in 1993.
