In 2004, she started working for ESPN as a reporter for National Hockey Night. Soon, she took on sideline reporting duties for both college football and major league baseball. By 2007, she was named "America's Sexiest Sportscaster" by Playboy Magazine.
She had already made a name for herself in the sports world, when a peeping Tom scandal thrust her into the national spotlight in 2009. Footage of Erin naked in a hotel room was released online, and the stalker was later arrested and sentenced to 30 months in prison. Erin told Oprah that she thought her career was over because of the scandal but added, "I also feel it's my duty to come out and show this person, you know what? I worked hard for my career and I — I got there the right way, and you're not gonna break me down."
