Fearing that a continuing dispute will prevent 900,000 local Comcast customers from watching regular-season Yankee games, the Yes Network is beginning a campaign Wednesday to try to persuade affected fans to switch to providers like Verizon Fios and DirecTV.

“We’re telling people that this isn’t going to settle,” Tracy Dolgin, the president of the YES Network, said in a telephone interview. “Hope is not a strategy. You have to find another provider.”

Comcast dropped YES from systems in New Jersey, southern Connecticut and Scranton, Pa., in mid-November, depriving customers of Brooklyn Nets games and various Yankee and Nets programs. But with the baseball season a month away, YES said it was appropriate to put pressure on Comcast with television, radio, outdoor, transit and print ads and messages on social media. Other networks have adopted a similar strategy during an impasse. YES has set up a website to argue its case and suggest alternate providers.

“We’re already into spring training,” Dolgin said. “There’s a real chance of missing both opening day and the season. To me this is a huge thing.”
